Next I removed the straps and re-inserted them so they're facing the right way :P.

I designed some simple picatinny brackets so this can be mounted on a gun. I marked, drilled, and tapped holes for these before assembly.

Speaking of the brackets, here's a neat trick I came up with for 3D printing lateral holes. If you make the holes tear-drop shaped, they can be printed without supports! I usually use a 55 degree angle for the top.

Annnd, it's done!

When mounted on a gun it has a reasonable profile. And the switch can be flipped without taking your left hand off of the fore-grip.

I consider the project to be done for now. But I have a few ideas for improvements I would like to make in the future.

* Automatic over-temp shutdown

* Temperature indicator

* Lower power, continous run mode
