Have a laser cutter? You can churn out Lyratron XRBGs (Experimental Rubber Band Guns) all day! We developed these pistols as Xmas presents for our bros, and as usual we decided to open source the design. It's a simple 6-shot step-up mechanism. We used 1/8" acrylic glass (plexiglass) and manually rounded the edges of the outer (stationary) band retention notches with a Dremel to improve reliability. Have fun!
- Lase SVG onto a single sheet of 1/8" thick plexiglass.
- Glue pieces together with hot melt glue, making sure to keep glue away from the sliding middle (trigger) piece.
- Once assembled, carefully round off the edges of the outer (stationary) band retention notches.
- Spray paint if desired.
- Lase and install wood grips if desired.
