A toy that will test the calibration of your printer.
All parts are oriented for printing and do not need supports.
The axles are in two parts that are spaced to allow them to be printed and still spin (with just a little persuasion). In my case, I need to use a razor blade to pop the two parts free of each other at the lower “gap”. I found that the spot where the layer changes happened is right where I needed to apply pressure with a blade. Do not let the slicer apply any supports or move the two parts away from their current orientation!
The wheels slide onto the axles without the need of glue. They are tight, but fit.
The axle assemblies require glue be held into the chassis.
The author marked this model as their own original creation.
