MPCNC Primo Dust Shoe and core Z clamp mod

thingiverse

Edit March 28, 2021: Added (No Cutout) versions of the top and shoe as well as the matching Fusion 360 files for anyone who has smooth rods that are solid end to end. This is a dust shoe I designed to work with my MPCNC Primo (C version) and an old shop vac I had around. I have included the modified Z clamps used to mount the smooth rods and fix them in place. The smooth rods are 8mm and my rods had cut outs at each end so the dust shoe and top clamp have notches for those cutouts but you can remove the notches if your rods don't have the cutouts. I used M3 10mm screw and nuts to fix the rods in place and it will slide up and down independent of the z carriage as long as you leave the middle screws loose and you can tighten them to fix the shoe at that level just to be safe though the rods are held in place very well by friction in my case YMMV. I added spokes to the bottom of the dust shoe since my first few attempts the center moved before comletion. The models should all now print without support but I left a cutout on the bottom of the dust shoe rod holes because my rods also had the option to clip a ring on them to hold them in place, you can remote that cutout if needed. You may need to flip the bottom Z mounts (the ones without the screw holes) to print them easier. I may upload versions without the cutouts for the bottom of the rod holes and the notches on the tom and bottom of the rods if I have time. Designed in Fusion 360, files included.
