About this 3D model
This is an aluminum plate that mounts on Greg's x-carriage. This could be made out of a lot of materials, but I milled this one out of 6061 .25" plate on a CNC mill. Using aluminum makes it act like a heatsink as well as a mounting plate, and keeps the top of the groovemount nice and cool, avoiding issues with melting extruder bodies (you folks making em out of PLA, imma look at you).
