This is a catapult that fires Nerf Rival rounds.
Some superglue is required for assembly. The spin rod itself should not be glued, it
can be inserted in any number of holes, raising or lowering the trajectory of the catapult.
This is one of my earlier designs and can probably be improved upon a bit. Care must be taken when printing or it will break after some use. Filling in some of the struts used to make the body should make it easier to print.
Added a "filled in" version that should be easier to print at 0.2mm layer height.
Uses springs from a spring kit like:
