Doorbell back mounting plate

This is a backing plate for a doorbell. Unfortunately, I can't really be much more specific than that, as the doorbell itself has very little in the way of markings to help identify it. While replacing the batteries in ours, one of the tabs on the original mount broke off, so I threw together this design to replace the original.

Hopefully the design can be useful to someone else out there.

The print settings I used are included below. Most of them probably aren't all that crucial, although I would recommend using supports on the tabs that lock the front of the doorbell onto this backing plate, at least.
