Summary

I needed a simple housing to hold a specific size clock, flush to the surface.

This holds the clock pretty snuggly and flush for a specific purpose. Printed, it lays down and is roughly the size to lay flat under a computer mouse.

The hole in the bottom allows the removal of the clock or for repositioning.

Cheers.
