Inspired by some laser cut projects on Thingverse I made this crossbow for my son. It uses a rubber band and has the gun lock built into the handle. It will shoot a sucker dart across the kitchen and stick it to the microwave with a satisfying smack.


Cut from 3/16 and 1/16\" sheet. I used cheap plywood from the home center and cut it out on the scroll saw, but it needs a laser cutter to make it smell right.

Cut out the parts.
Insert tab A into Slot B... Etc.
The prototype didn't use any glue or fasteners except for some toothpicks to connect the linkage from the trigger to the rubber band catch.

can u pls make it a stl file

Thank you I made one :-D

Beautiful. I need to trade a lung or kidney to get a Lazor.

i might expirement with the design to make it use mags...

Hey, it looks Really Great!

What scale is the dxf file? How do I print it out the right size?

The scale should be 1:1.

thanks so much for uploading this file! i've now build two, both slight variations on your design. they work great! now i'm experimenting with different types of ammo...

Beautiful. There is something about laser cut wood that just makes me happy.
You could likely get this to shoot marbles if you adjust the "barrel" to fit.
What thickness is your plywood? It looks much more substantial than the one I built.

these i made with 3/16" plywood which worked great. i've since made more from 1/4" ply and MDF which also worked fine. i'm working on finding the best ammunition now!

oh, did you use glue or just press fit?

i did use glue

Now printing one of these has to be on the cards, right? I'd do it if I weren't trying to get stuff ready for LCA2010 next week.

Sadly, I do not have a printer. I think laser cut plywood is the way to go. A crossbow should be made of wood right?
