Trebuchet

A beautiful working trebuchet to throw around small stones, sweets or whatever...

Use some coins to fill up the piggy bank counter weight. 

You can print every part with standard settings. No support or raft needed.

Additional parts needed:

• 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 (4x M3x5, 12x M3x20)
• two small springs
   

That's how it looks like in slow motion - it's real fun to play around with it:
