wedge_catapult_1

thingiverse

The catapult's components are a base, catapult, and trigger. A wrapped elastic powers the catapult around the wedge. This design was created to practice using shapesmith.net tool. The print size is uncertain. If scaling prints, ensure the large pivot fits standard steel or aluminum rod dimensions. My first 3D model; awaiting printer assembly for testing. Elastic secures the top dowel in place on the indented wedge and base. The trigger ring allows string or trip wire attachment... for mischief!
