Summary

This is a box for mounting a large red button that I used for a gate.

The button purchased is a 30mm mushroom head button from Uxcell from here:

For mounting, I used #8 3" deck screws.

No supports are needed but there is a 0.25mm layer that bridges the large hole that will need to be removed after printing.

The Sketchup file is included.
