Convoy 3x21D handle with switch actuator

This is a handle for the Convoy 3x21D flashlight that allows single-handed operation and prevents conduction of heat from the flashlight body to the users hand.

I strongly recommend using a heat-resistant filament.  I used Overture ASA; PETG might work.  If printing in ASA, I recommend scaling the model up by 0.5%.

The bores for the switch plunger need to be reasonably smooth to keep the switch from binding.  If your plunger doesn't move freely, try cleaning the bores with a 23/64 (handle) and 7/16 (yoke) drill bit.

Hardware required:

4x M3x5mm button head cap screws

2x ¼-20 x 3/8 button head cap screws
