Summary

My 1/16 DIN temperature controller locking cover.
It uses a cam lock in the lid. See the picture for dimensions. I used the smallest (shortest) one I could find. And (2) 3X20mm socket head cap screws for the hinge. And (2) 3mm brass embedded nut inserts. It will work with or without the inserts.
There is a pretty long bridge for the locking tab so I added a support in the middle. Trim away post print.
