About this 3D model
I started with http://www.thingiverse.com/thing:224356 and made a few changes: * Made it bigger so I could mount a push-button on top. * Raised the mounting posts a bit so there would be more room for a longer screw * Moved the mounting holes to the inside of the enclosure * Made the retaining clip beefier - it broke too easily I've installed mine on the y-axis motor mounting plate so it moves along with the plate. Theres a lot less wiring this way.
