(Check the instructions for print settings) Demo: http://www.youtube.com/watch?v=rebuqoPh0BI&feature=em-upload_owner *I designed the spring in SolidWorks, but it was inspired by obijuan's springs: http://www.thingiverse.com/thing:21234 EDIT: I edited the trigger to make it fit a little better into the housing. Instructions This was printed with the following settings: Material: ABS / PLA Layer Height: 0.20 mm Shells: 2 Infill: 50% (hexagonal) Extruder Temp: 230C / 220C Plate Temp: 120C / 60C Raft: No Support: No Note: If you print this in PLA, pull the projectile back slowly the first time. The brittleness of the PLA may cause the spring to snap if it's compressed too quickly.
