Suckit dust boot surgery

I recently upgraded to the BeaverCNC HDZ, so I needed to upgrade my Suckit dust boot mounts to match the new Z axis. The Suckit site has a nice kit to do this, it’s affordable enough, BUT shipping to France and adding import taxes would have meant doubling the price, plus I felt bad about just throwing away the old parts, so I figured I would just cut new mounts inside the old ones

I first cut a jig in MDF to hold/center the old mount :

Then guessed a set fo feeds and speeds for the polycarb material (12.000 RPM, 700mm/min, and 0.7mm per pass, with a 1/8" 2-flute square endmill), and did a test cut:

Got nice looking chips and decent cut quality, so I took a deep breath and launched the actual cutting job (I had one shot…), and got this rectangular mount with two new holes.

Repeated the jig cut & mount cut for the other (left) mount, and finally 3D-printed a set of spacers, assembled everything on the HDZ, et voilà !


Nice! Now I’m inspired to do the same.

Very nice solution. I ordered the ears from Carbide and the new spacers from suck-it. Have the ears and expecting spacers tomorrow. If not happy I may attempt what you did. Could have the $60.00 for parts and shipping between the two.:crazy_face:

Very nice job, way better then spending a bunch and waiting forever! Does anyone know what that glossy black plastic material is called, some kind of pvc plastic?

I think it’s just black polycarbonate, or at least it mills similarly.


I was really impressed when I thought you were milling the STEEL versions; still cool. That said… these are NOT the steel rabbit ears mount that come with the current pro version of the suckitdustboot. FWIW.

Absolutely. My Suckit is from two years ago and my HDZ is from the BeaverCNC ages, so both designs have changed a lot since then.
