8020 1010 5/8 inch post

For a project at work I needed a 5/8" post that would slide into a 1010 profile piece of 8020.

This was designed with OpenSCAD.

When I printed it I needed to use supports to maintain the roundness of the post.

I leveraged LorenIPSVM's "M3 screw 8020 1010 t-slot" for this project. https://www.thingiverse.com/thing:109272
