Description

A fully 3D printed catapult, prints flat within a card, so it fits in a C5 envelope, fairly powerful, lots of fun!

Why

Designed to be printed flat, including all the parts required for assembly.

It’s a fun little toy, great for launching sweet wrappers or whatever else you feel like. I designed this to be fully 3D printable, and fairly powerful. I also wanted it to fit through a standard letterbox, so I could send it to my friends in the mail as a surprise.

Ensuring the sides would be strong enough, to stay connected to the base and top support during use took a few prototypes. I settled on a push fit, bump location method to balance joint strength and printability. It requires a bit of force (or some gentle hammer taps) to push them together initially but when located the joints are nice and strong.

Note: This model works great in both PLA and PETG. However, I just printed one of these in Prusament PC-CF. It has a bit too much power, the back pins of the sides started to come loose after a few shots, but a little superglue solved this!
