About this 3D model

This is a simple ball in a box puzzle. The toy is classically made in wood, but a 3D printed one is almost as cool. Update 2/16/2021: Included a STEP and resized STL model with units in mm. The original model was created in inches, prior to mm becoming the standard for slicers. This should fix errors users have of the model being 25.4x too small
