Pew pew!

I’ve been working on a printable open source snap-together disc shooter for a long time now.  I think it’s time I brought in some help.    I’ve decided on my own Thingiverse challenge.  The chosen design will receive $50.00 from me via PayPal.  Here’s the low down:

Rules:

• Design a printable, multiple capacity disc shooter that uses printed plastic, rubber bands, and, if you wish, up to one metal spring from a Pez dispenser
• The discs should be 19mm in diameter and 2mm in thickness
• The disc shooter should be tensioned by the trigger, rather than having to cock the shooter for each disc
• Needs to be printable on a MakerBot Cupcake CNC or Thing-O-Matic
• Needs to be posted to Thingiverse with an open license by 11:59PM on August 31
• Tag your Thing with the word “pewpew”
• Multiple entries allowed, so go wild

The entries will be judged using the following criteria:

• Number of Likes on Thingiverse
• Number of times it has been made by someone else (so post your ideas early!)
• Printability (not just fitting it in the space but also how many separate prints are required)
• Effort put into documentation and design (based on testing and revisions)
• Bonus points for:
• A snap-together design
• Parametric design in OpenSCAD
• Use of a removable magazine for holding discs
• Easy-to-pull trigger
• Uploading STL’s for printing plates

Good luck!  I can’t wait to have a big pile of multi-colored disc shooters!
