Robust Derby Car Axle Bender

thingiverse

Note: the STL files were originally modeled in inch, so a conversion may be required for your slicer. This design is intended to be a robust, easy to use axle bender for Pinewood Derby car setup. The design is two printed parts and a 3/16" diameter, 1.25" long dowel pin (McMaster 98381A512, for example). I originally intended this as a proof of concept, but it worked without any printing adjustments. Build orientation is important to keep the strength. The design is intended to bend the axle around the dowel pin, which sets the bend exactly where you want it. A slot was used in the static part so that you can get a tool under the axle head, but I didn't see the need to use it.
