This is a series of parts intended for use building a marshmallow catapult. Its construction also requires 3 skewers and numerous rubber bands, as well as some glue.
Edit: Accidentally had the parts double sized. Whoops!
Edit 2: Maya exports things sideways. I don't know why. Hopefully I fixed that too.
Edit 3: Maya and Thingiverse don't like each other, so I had to edit the files again in TinkerCAD. Hopefully they're okay now.
