Wind-Up Engine V1.2 Updated - Fully Printed

thingiverse

A 3D-printed engine prototype uses a captured and released spring's energy through a series of gears. The current design shows promise, but improvements are needed. For the spring, print in ABS with zero fill layers, zero infill, and four extra layers (though PLA settings aren't specified). Cut it at obtuse angles to create two springs, then place them inside the case alongside the drive gear, aligning its teeth groove with the case ridge. Attach GearIn1 in the leftmost hole meshing with the drive's straight teeth. The GearFloater goes next, gluing its pin before positioning GearOut1 and two GearOut2s in subsequent holes. Secure the HolderPlate and holderArm around the output gears, ensuring pegs hold the gears in place. Glue a key in the hexagonal hole of GearIn1. When wound up, the engine should release gears at gradual rates; however, output speeds remain unknown, and frequent spring replacement is suspected. If successful, it may power actions briefly.
