CTS Starter System Speaker Mount

Our local pool's Colorado Timing System starter was damaged, somebody probably dropped it. The speaker mounts were all broken, leaving the speaker driver to flop around inside the speaker horn and fall out.

This is a mount designed to capture and hold the speaker driver in place so it can be screwed to the speaker horn.

My print volume is only 125mm^3, and the speaker horn is 135mm at the widest, so a single piece is too large. This prints 3 pieces that can be screwed together with whatever screws, washers, and nuts you have laying around.
