Catapult

thingiverse

This is an untested model. To ensure full functionality, the base must be printed twice. Three sturdy dowel rods are required to provide structural support. Two precision-crafted arm locks will maintain the arm in its firing position with optimal stability. If you downloaded this design prior to December 21, 2017, the arm may not withstand repeated shots due to potential weakness. To guarantee stability, print the dowel rods as solid parts.
