Meetings & Events


All Castlemakers events free and open to all unless otherwise otherwise noted.

In  June & July Open Shop at the Makerspace (19 E. Franklin) is on Saturdays from 8:30-12 pm. You can bring a project to work on or just visit!  See our four 3D printers, laser cutter/engraver, new desktop CNC mill, hydroponics,  Arduinos/Raspberry Pi’s, & use the 1 building/making library. We’ll also be open for First Friday (7/6) from 5-8 pm.

Our next Castlemakers Kids meeting will be Saturday, June 23 from 3-5 pm, celebrating ARRL’s (Amateur Radio Reference League) Field Day. We’ll build an emergency wire antenna using a piece of coax cable, then join 35,000 other Ham Radio operators operating on Field Day by making a radio ‘contact’ with someone else using your antenna. We’ll drive over to Putnam County’s EOC at 3:30 to build the antennas & join the fun.

The Castlemakers CoderDojo, a free, volunteer-led, community-based programming club for young people, meets the first Saturday of every month. Our next meeting will be Saturday July 7th from 1-4 pm at 19 E Franklin St. Drop in anytime during that period to learn coding, work on a project or just have some fun…

The next 3DPO (3D Printer Owners) Meetup will be part of the  Rose-Hulman Ventures road trip, it will include seeing their 3D printing and other fabrication equipment. Join us on July 11th at 3PM (leaving Greencastle at 2 pm) to get a tour of perhaps the best rapid prototyping, product development and design firm in the Midwest.

Castlemakers Classes!

  • On June 21rst at 6:30 pm we’ll continue our Design to Product series, this time on 3D printing. We’ll cover in a  little more depth what makes a good (AND bad) 3D printable design, showing you some examples of both. You’ll get a chance to design a small item in this class. See the classes page for reservations & more details.
  • July & August will be classes on designing products for Lasercutting and desktop CNC machines.

Putnam County Events

  1. hi, I have 2 questions; are kids welcome on Tuesdays and are code dojo sessions still being held on the first Saturday of the month?

    1. Definitely on both! Kids are welcome anytime we have open shop (Tuesday nights for now), in May when the Farmer’s Market opens downtown we’ll have the makerspace open Saturday Mornings also.

    1. Hope for late July/early August. Our plan is letting folks make an acrylic keychain or we have some interest in building Dice Towers. The original design software we were going to use needs a laptop at least, which we don’t have enough of to do a class. But working on a way to use Chromebooks, a recent gift we received from Techpoint Foundation for Youth.
