This bolt action, magazine fed desk toy has the potential to shoot a whole 1ft! (Maybe 2ft if you're a lucky duck). 

Realistic TEC-9 action!

  • Double Feeding!

My first functional project modeled from scratch in Freecad, so go easy on me. This still a work in progress but i will continue to update it and make a build guide. 

Functional at 80%-100% Scale, has not been tested below 80%. Almost 1:1 scale at 100%, but is quicker to print and still functional at 80% Filing and sanding will be required to ensure things move smoothly, especially with the bolt, but printing the bolt 1-2% smaller than the barrel will help to mitigate that.

Be smart about this, never brandish this as a real weapon or bring it out in public, this is a toy modeled off of a REAL LIFE firearm, treat it as such. Just because you know it's a toy, doesn't mean other people will. Enjoy and be safe.

PRINT ORIENTATION: All files except for the trigger will need to be reorientated in the slicer, refer to the screenshot for optimal orientations.

PRINT SETTINGS: 

Layer Height: 0.16-0.20

Walls/Top Layers/Bottom Layers: 4+

Infill: 15% minimum 

  • I recommend using 100% infill on the bolt, charging handle, mag catch, trigger and bolt latch.

Supports:

  1. Barrel: Standard supports, 10% infill.
  2. Frame: Organic/Tree supports, No infill.
  3. All other parts should be printable with no supports, but may need to be used at the printers discretion.

OTHER PARTS: (These parts only fit when all printed parts are scaled to 80%, you will have to get creative with springs and M3 bolts otherwise)

  • Bolt Spring - Length: 48-52mm, OD: 10mm, ID: 8.5mm, Wire: 0.8-0.9mm.
  • 2x Magazine Springs (Same as bolt spring)
  • Magazine Catch Spring - Any old pen spring cut-down will do.
  • Trigger/Bolt latch Spring - Pen Spring
  • 3x 25mm M2 screws (Can be substituted with printed “Structural Pins”
  • 1× Short M2 screw for firing pin
  • 1x Short M2 screw for charging handle support.
