Secure groovemount plate

I created a very basic groovemount plate in two pieces that can be used together to secure a hot end such as the Hexagon hot end.

The standard aluminum plate doesn't prevent the hot end from sliding forward. Normally, you would have an extruder or guide but I preferred to have this very simple two-plate system instead. This makes it easy to mount the hot ends in a Bowden configuration on a standard mount.
