Micro Catapult V2.0

This catapult is a remix of the excellent and famous Micro Catapult by LukeTansell!

There is one major improvement over the previous design: instead of having the tension bars fixed at one side and hinged at the other side, here the throwing arm and the trigger are attached to tension bars fixed in the frame on both sides!

This allows for several advantages:

• easy printing: one solid part without demanding tolerances to be met
• double the length in tension bar equals double the mayhem!
• no sliding friction thus even more mayhem!
• fully ambidextrous design

Seriously: even it's of comparable size, this catapult is much more powerful. Catapulting small projectiles about 2 meters up and several meters in distance should be possible. It's probably a good idea to supervise smaller kids when they play with this toy!

Also added an easy-to-print projectile of appropriate size and weight.

Printing:

All parts are print-in-place. No supports or assembly needed.

Prints and shoots fine in PETG, ASA or similar materials. Don't use PLA. PLA is too stiff and brittle and the catapult will break easily!

Please note! This design was not made by me but a young CAD beginner with a little bit of help from my side. Please excuse any rough edges or minor mistakes you might find.
