A nice working trebuchet to throw around small stones, sweets or whatever...
Use some coins to fill up the counter weight.
You can print every part with standard settings. No support or raft needed.
Some additional parts are needed - there is a picture that shows all the parts you need:
- M3 threaded rod (cut to 60 and 380 mm)
- 10mm tube (cut to 35 and 45 mm with 3mm holes in the middle)
- M3 nuts, washer and screws
- two small springs
That's how it looks like in slow motion: https://youtu.be/s_eITNoklZY
