Inspired by [https://www.thingiverse.com/thing:4769678](https://www.thingiverse.com/thing:4769678) and made before I knew [https://www.thingiverse.com/thing:1612914](https://www.thingiverse.com/thing:1612914) existed. Designed in Fusion360 after measuring with digital calipers and a few test prints/fits for dimensions.

USE PETG! PLA will deteriorate quickly with the heat.

Highly recommend 100% infill with 4 perimeters. Infill is tweakable if you really care but I wouldn't print less than 4 perimeters. 

You can print without supports, just use a razor blade to trim the hanging material. The bolt head should press fit perfectly into the indent.
