MTLOJ Mostly Tooless Locking Oversized Jolt

Update 7-13-26: added f3d file

An actually printable version of Captain Slugs TLOJ.

There a 2 versions to print this in. Secret shot mode or regular jolt mode (but why dough). The secret shot mode uses the topper with no hole and plunger with hole parts. The normal mode uses the topper with hole and plunger with no hole. These parts can be swapped out without tools, but takes a while to disassemble. 

The step file is a decent indicator of how to assemble it. 

 The trigger and plunger sides needs to be made of stiff material and lots of walls. The catch plate needs a lot of walls, too

I think there is supposed to be an o ring before the barrel in the plunger, but I could not get mine to fit. I think it's either a 011 or 012.

-Hardware that requires measurements or is not in the step file. Other parts are regular slug parts. 

4 inch plunger tube.

4.5 inch threaded rod

4 inch 788 spring

3/32 elastic for the catch 

3 inch barrel for the bottom and top . Make sure the one you are shooting out of can hold darts not too tight and not too loose. Mine is a 13mm barrel.

a cotter pin for the barrel pin

Credit to taffy for sharing the step file to make this work.
