This is a E3D V6 mount for the MPCNC machine by Allted.
It mounts on the original tool mount using two of the #8 bolts and lock-nuts.
Mount it in the 2nd to last holes from the bottom, if you want more Z height you can edit it to move the hot end up farther but you will need a slimmer endstop mount.
Also dont mount it in the lowest set of holes as it robs Z height and induces Z wobble.
2x M3 bolts
2x M3 nuts
The clamp piece only fits one way so if it doesnt fit swap it.
The bolts that thread into a nut in the nut trap. If the nuts spins use a screwdriver to hold it. However the bolts dont need to be crazy tight, as it clamps very well.
