A New Beginning

Leave a comment

The makerspace has landed at a new location at 8 N Jackson Street in downtown Greencastle!

Moving is always a ‘project’, especially when you have to put things into storage then move it to another space. We’ve still got a lot to do, but we’re really excited about our new location on the square across from the Buzz Bomb.

We’ll be moving in gradually, there’s a few things that still need to be completed in this historic building. It is slightly larger and much more open than our last location, which means we’re still figuring out how to arrange things. And of course when you have tools and equipment like we do it takes some time to setup and reconnect everything. But don’t prevent you from stopping by, we’ve already having Open Shop hours in the new space. Look for a future event announcement after everything is out of storage and more organized.

We’re incredibly grateful to Putnam County Museum for finding us a place to temporarily store things – good storage is hard to find! And also to the Putnam County Public Library for letting us use their conference rooms & store a few speciality equipment carts so we could continue to operate.

Helping Other Organizations

One of the things we are proud of is trying to help other organizations when they have a problem or need. So when we got a text about Greencastle’s Parks & Recreation Department needing help in using a recently purchased Computer Numeric Control(CNC) machine, we were more than willing to oblige!

The first peice we helped Greencastle Parks & Recreation to make on their CNC.

It turns out they had gotten the CNC to engrave pickets for the Emerald Palace 2.0, the playground in Robe Ann Park that was being refurbished. Donor names were going to be put on the picket fence around the play area, but having trouble with using their new CNC to get the job done.

We’ve have a CNC at the makespace, although a different manufacturer, and alos teach classes on how to use a CNC, so glad to help esp since several of our members have a CNC in their home shop also.

Castlemakers helped them get their CNC cutting material once they got the right software and plugins to use it.

One of the things we’ve learned over the years in using and teaching others their operation is in general and specifically for some manufacturer’s there’s a lot of tacit knowledge involved in using one. While a CNC can look relatively inexpensive to buy one, like a lot of other things, without the proper knowledge and software you can get overwhelmed pretty quickly. Or depending on the project it can get expensive quickly by breaking bits or ruining the material you’re using.

After helping them figure out the software they needed and some quick ‘lessons learned & what to watch for’ from one of our more experienced members, they got the job done & the playground is now open. Makerspaces can provide, knowledge, experiences, and assistance to others – along with a lot of other things to help you get things done!

What Happened to Castlemakers?

Leave a comment

We’ve had an eventful year since January! You might be wondering what happened if you recently walked down Franklin Street and just looked in the windows. After nearly 10 years at our Franklin Street location, an ownership change meant we had to find a new location for the makerspace. And fast.

It’s been over 10 years since the makerspace was this empty!

Unfortunately with the sudden change and timing, it left our board with some tough calls. We made the difficult decision to put everything into storage until a suitable new location was available. We’ve finally been able to find some alternatives, with hopes to a new physical location settled next month. Watch for an announcement soon of our new location.

We continue to still operate thanks to some quick scrambling, our members, & the Putnam County Public Library(PCPL). Three of our frequently equipment items are now on carts that we pull out when meeting at the library. And have been doing classes at the library laso.

And of course we still have perhaps the most important element of a makerspace: the knowledge, skills, and experiences of a makerspace. Drop in during our Open Shop hours when you get a chance!

3D Printing, Classes

Holiday Classes – Glass & Plastic

Leave a comment

Around the holidays we try to offer holiday themed classes & this year was no exception. In December we chose to offer another glass fusing & slumping class to make glass ornaments along with a requested 3D printing class.

We’re still learning and experimenting with the kiln donated last year. In the glass fusing class we were able to add some new materials in this class, glass Frit. It looks like colored glass pellets, and for folks that sprinkled it on their designs before fusing it gave an interesting effect. We used a high enough temperature with the kiln that it frit was really absorbed in the base glass, but we’ll be doing more experimentation in the future.

In this month’s 3D printing class we also did ornaments, like what we’ve done in the past 10 years. The folks attending were interested in the basics, so that’s what we did. But 3D printing has become a lot more popular and techniques have advanced significantly, so we’ve been considering offering a more advanced class or one that gets into more depth and advanced techniques. We could also offer a liquid resin 3D printing class if there’s interest, let us know if you’d like us to offer either class.

Entrepreneurship, Greencastle's Makerspace

Encouraging Entrepreneurship

Leave a comment

One thing we haven’t talked a lot about is the makerspace Entrepreneurial Fellowship program. It’s a program to encourage entrepreneurship from the ground up. Over the years we’ve had a number of people come into the makerspace wanting to produce prototypes or make small quantities of something to sell – items they made can still found in shops locally and online. Our idea is to discover and support more people that thought about selling or making a product or service, then help them to actually do it.

Thanks to a partnership with Main Street Greencastle, and financial support from the Indiana Economic Development Corporation(IEDC), we’ve formalized a program that supports and encourages people to take the next step in creating a business. Many people hear from others they should offer a product for sale or think about selling an idea they made. We’re helping start more cottage industry businesses that sell products at markets, through other stores, certainly online, and that might grow into something bigger.

At the core of the program is access to makerspace tools, resources (including entrepreneurial makers), and other resources they need. We’re innovating with them along the way to determine what works best, not surprising that this is a new/possibly first of it’s kind program. It’s certainly attracting some interest, not only from IEDC’s Community Collaboration Fund, but we were also featured on Inside Indiana Business when we started started the program. Our first cohort group is now filled and we’re planning a second. If you’re interested please read this program description and fill out an application!

Talking Pumpkins

Leave a comment

For many years now at Halloween we’ve helped Putnam County Library for the Scary Science exhibit in the Kiwanis Room downstairs. We are often there 3D printing bats or witches hats, explaining how it works, or sometimes giving away laser cut ghosts and goblins. Last year we added a ghostly optical illusion using a technique called Pepper’s ghost to project holograms.

This year to try something different we 3D printed a pumpkin and then projected a talking face on it, which turned out to be another great illusion. By using a phone to project the face, most folks were looking behind the pumpkin or asking how we did it!

The idea is based on a project from DIY Machines, who deserves full credit for coming up with a great makerspace Halloween project idea. Unfortunately it’s a bit complex and pretty time consuming project, although we’ll incorporate more elements of it next year to display at the makerspace. And it was designed to be an outdoor display, while at the library we were going to be using it indoors. But having enough time to do it was the real limiting factor.

We used a cellphone projector indoors so most folks didn’t notice how it worked.

We went ahead and printed one of the pumpkins in orange and then realized we could project the face on the pumpkin using a projector attachment for my Moto Z phone. All we really had to do was lay the phone on the table across from the 3D printed pumpkin to project the face on the pumpkin.

2025 Putt Putnam County

Early arrivals at Putt Putnam County in 2025

With a record number of mini golf holes, this year’s event exceeded our expectations with 24 community built mini-golf holes. People started showing up as quick as we could get the holes set up – it was a great evening for everyone to play mini-golf. With perfect weather the crowd grew into the largest I’ve seen yet!

It didn’t take long for lines to play appear by Indiana Street.

There really was so many creative mini-golf holes, you really can’t describe them all. This year we added a section for the pre-engineering high school class and some of them certainly raised the bar with lights and moving parts. And while they were popular, many of the simpler holes were still big hits with the players. And in many cases simple paid off in that they held up better and were still operating as intended at the end of the evening.

Scouts troops 99 and 999 had mini-golf holes near Vine Street.
Holes extended to Vine and Franklin Streets with Scouts Troops 99 & 999 anchoring us on one end.

Which points out one of the many things folks learn from making something and then using it. Of course there’s the challenges of working with others, almost all of the holes were built by a family, group, or team of students, and the inevitable compromises that have to be made when you’re dealing with a deadline.

And by the end of night we were treated to an extra special surprise, fireworks! What a great way to finish up, can’t wait to see what next year’s event brings…

Mini-golf holes lined down Franklin Street for Putt Putnam County.
Putt Putnam County 2024 had plenty of mini-golf hole challenges.

It’s that time of year when we host our annual mini-golf hole building event, Putt Putnam County. It’s hard to believe that we started this event back in 2016. Last year we had a total of 16 community built mini-golf holes lined down Franklin Street for anyone to play on a Friday night.

I had too many favorites to just pick one or two. Greencastle High School’s Ghost Pirate Ship was certainly one of the most elaborate builds last year, you could even ‘putt’ the plank. And luckily there wasn’t enough power to vaporize the golf ball on Laser Alert! And some difficult ones too, I only saw one person get the ball up that guitar neck and into the soundhole. It hard to resist hitting the golf ball through downtown Greencastle on the Virtual hole, except of course for a few closed roads. A few favorites from previous years were there too.

It’s not to late to plan and build a hole for the 2025 event on Friday October 3rd. It doesn’t take long to build one, full details are on the Putt Putnam County webpage, and we’ve had some previous tips about making one. And if you can’t?

Please just show up and play a round on Friday night from 6-8 pm, it’s great family fun for all!

Making a Splint

Leave a comment
3D printed finger protector
Finger splint/protector that was scaled up to fit.

After injuring a fingertip, leaf blower intake fan blades & fingers don’t mix well, I was looking for a splint to protect my now injured index finger. Couldn’t find one in the medicine cabinet at home and was thinking about going to the makerspace to get one out of the first aid kit there. Of course a friend mentioned that he figured I’d just print one. Of course I could!

So did a quick online search and found one that was an easy 3D printing job. After taking some measurements of my finger (don’t forget to take into account any bandages), then scaling up, 25 min later I had a custom fit finger protector! It’s worked great, I got to pick my own color, and doesn’t look bad if I do say so myself…

MRRF 2025

2025 Midwest Rip Rap Festival (MRRF) in Goshen Indiana, inside the main building

Last weekend I traveled up to Goshen Indiana for the Midwest Rep Rap Festival (MRRF), a trip every 3D printing enthusiast should make. It’s been 6 years since I went to MRRF, and it’s certainly grown since then! One big improvement: more space! When I went in 2019 it was so crowded it was difficult to walk around.

By no means the only 3D printed castle there, but often the most crowded table in part to the life-sized figurines including girl on the right with pink & gray hair.

The annual event has changed slightly, although the biggest portion is still regular folks showing off what they’ve made. It does seem to have shifted more from new/unique 3D printers to what you can print, but there were still some different 3D printer designs there. There were several interesting belt printers, a few variations on the Positron printer, and a new Bondtech multi-material upgrade unit that looked really promising among others..

Death Racers at MRRF 2025

There were also many vendors there: Prusa had a large presence there, Polymaker had one of the most challenging tables with their interactive filament color guessing games, and Indiana based Atomic Filament had lots of filament at the show. And even some youtubers with tables, occasionally doing interviews, and of course a few vendor raffles (I won a Voron board from LDO Motion!).

Turtle on the right (with Tiny Bikes to the back left) took 15 spools of filament, 82 pieces, and 350 hours of print time.

But what I really noticed was the increase of the activities vs 2019, there was even a separate building for setup, repairs, and the competitive challenges. Death Racers, jousting in small tank like 3D printed cars where you knock off the head of opponents, were quite popular and Mayhem at MRRF continued this year. Then there was an occasional Tiny Bike parade in the main building and 3D printed drag racers outside in the parking lot.

Perhaps what impressed me the most was the congenial, family friendly atmosphere of not only the participants but also the attendees. It will definitely be on the list to attend next year!
