Hey everyone,
I've got a grip design that's ready for beta testing.
It is only ~10 degrees off from perfectly vertical, so the hole for the grip screw would normally end up right in the middle of the backstrap. To get around this, I made the backstrap a separate component that is pressed into the front of the grip after being screwed onto the receiver. This also allows you to easily make the grip two-tone or potentially print the rear in a firm rubbery material for extra comfort.
I'm not quite sure the exact procedure people use on this website, to be honest. If you're on the deterrence dispensed chat, the beta files are already up there
