trebuchet alternative plastic parts

thingiverse

The trebuchet design from Thingiverse impressed me as the most suitable, but it seemed over-engineered for a toy project. I opted not to search and purchase 10mm tubes; instead, I printed them myself, which worked out well. To simplify things, I skipped using an M3 rod along the beam's length and used M3 screws at both ends instead. Feeling lazy, I didn't design a new counterweight, but I did modify the coin slot to allow for any additional weights I wanted to use.
