Description
5 piece desk catapult. The drive shaft and thumb screw are only needed if you want to tie a string around the arm and have it act as a winding mechanism.
For assembly, you need each part, and three lengths of 5mm metal or plastic rod. (I used 5mm aluminium). Everything press fits together.
Aside form this, you will need some elastic bands to power it and it's done!
