Tic Tac Gun Rubber Band Edition
Have us print this for you
PLA from £6 inc. UK delivery on letter-sized prints. We slice, print on a calibrated Creality K2 / Bambu A1, QC and post.
Really enjoyed the Tic Tac 2 build but wanted a more powerful option without the spring. This remix simply adds a post at the front of the gun for attaching a rubber band in lieu of a spring.
Do note that in cases where a very strong band is used you may need to beef up the infill of the firing pin mechanism. With this mod I've easily launched a tic tac across a small room.
NOTE ABOUT STL FILES: If you've already printed the original TTG2 all you need to print is the left side STL file (TTG_LEFT_RB_V2.stl) to use this mod. The other files have been included in the event someone is starting from scratch.

Update: Uploaded a modified right side as requested for recessed M3 nuts (Right_Side_M3_Nut.stl)
Update2: Updated the left side model slightly to have a smoother band transition from the post to the body of the gun. I was noticing some band wear on my test gun at this point so this should help with that. Removed the original version as it's now redundant.
Update3: Increased the diameter of the Right Side M3 nut recesses by 0.3mm
