Of course.. Since it's being brought up to speed for making what I'm
selling, it is already going and just needs a new mount, then I'll get
some video up..

Here's some pics though for current state. Flat side plate of one box
at the bottom, top is cut out to take the Dremel case. Side plates in
the middle were removed, cut the front welds and broke the back one,
should be able to use a 5lb sledge and chisel to break all 3 for speed
after I make something to hold the boxes. On top of the top plate will
go a plastic plate, cut to fit the Dremel tightly at that level, and
with oversize holes and screwed to the top box to shift the plate for
alignment. Bottom plate will get a hole for the nose, stick it through
and tighten the collar back up on the other side, hole takes the load.
Plastic plate for the top will be fine, since it'll have so much
leverage against the tip, also these are stacked for picture, they'll
actually be a little further apart for max leverage. Should end up
being better than any $3 Dremel mount I've ever seen, most are terrible
or expensive. Screwed to the board after taking off the blue box in the
third picture..
Remounting the bottom rails and Y motor mount onto 2"x2" wood to get
some more height, plenty of travel in Z and the clearance will make
things easier. For X axis, a box over and side clamp to the coupler
nut, similar to how Y is clamped to the rail, and then things should be
pretty decent. Bracket has a little too much flex, not that bad but a
box will be better and the side clamps are much simpler to build.
