Door handle generator for round magnets (for the Prusa Enclosure)

Made a Customizer which produces door handles for the Prusa Enclosure, specifically for use with small round neodymium magnets.

Since these magnets seem to be available in an incredible amount of different sizes, I've made it so that you can specify :

* magnet diameter
* magnet thickness
* thickness of the acrylic/plexiglass sheets that you are using

and the Customizer will make you the appropriate door handle :)
