By the 6 parts, I assume you mean the motor assembly? Sure. I had been trying not to give too many “options” for fear people would go and print every STL, resulting in duplicates, but I’ve now uploaded the motor brace assembly as individually-printable STLs. Look for a sub-directory under “Project Files” named “individual files” and you’ll find a variety of STLs for the individual parts, one-per-file (usually–there is one with both left and right braces for convenience). Remember you need 3 cross-member braces along with the two main (left and right) braces.

(Note: I just checked the “all” STL and I see that the problem is there in the STL itself–the motor braces are too high. I’ve corrected and uploaded a new STL for future downloads.)

I’m not sure what’s going on with your print on the dust shroud, but I suspect your slicer software is part of the problem. It’s up to the slicer how to add supports, and usually, of course, the slicer leaves a several-micron gap between the support and the part to facilitate removal. Either the software isn’t doing that or, possibly, you are printing so hot that even with a gap the supports fuse to the part itself. My recommendation is to:

  1. try dropping your extruder temp a few degrees, assuming you have room to do it, and see if that helps. And/or:
  2. if you have access to an alternate slicer, try slicing the part in that software and see if it generates better (removable) supports.
  3. One other suggestion is to look at your generated gcode file in something like PrusaControl (https://prusacontrol.org/) and look at the layers view to understand your supports better. It won’t necessarily tell you whether there is a gap between the support and the part, but you still can get a sense of how the software is building support material, and it might give you an insight.
  4. Lastly, if none of the above work, you can DM me on the forum and tell me a) what your printer model is and b) your email, and c) what material you’re using, the bed/extruder temp you prefer, and any special settings your printner needs and I could try generating the gcode with supports for you.

FWIW, I use Slic3r PE (Prusa Edition), but I’ve had pretty good luck with Cura in the past, both are pretty good.

Apologies for the mistake on the “all” file I generated. I hope it didn’t make a blobby mess on your printer. And thanks for catching that so I could correct it.

Best,
