Simple String Shooter
thingiverse
This is my take on the popular idea of a string shooting toy, fully 3D printed. The original model by iksnijfpoedersuiker (Willem emmens) used 2 AA batteries. It is using two brushed motors pulled from old rc toys, simple TP4056 charging circuit and a single 18650 battery I salvaged from dead laptop battery pack. Works best with nylon string, and some foam laser cut rollers, but it kind of works with 3d printed plastic rollers too...
