About this 3D model

A coworker has some of these Automoblox cars for her children. Some axels have broken and she wokdered if I could print some replacements. She gave me a car to measure existing axels. These axels are for the Automoblox Minis. I designed this to print without support materials. I flattened one side of the middle ring since it isn't functional. I printed this with a 0.20mm nozzle at a 0.10mm layer height. This is a REALLY small piece.
