For the new year some of the M4’s clamp posts decided enough was enough:
No screw holes for me then.
So I 3D printed two of them as a single part, seems much better:

What do you think about making the STL file available? Thanks.

Try this - although it is a step file

Aloha,
- What material did you print these in?
- How was the part oriented on the build plate?
- What settings (infill, walls, layer height, supports, etc) worked
- How do they seem to be holding up?
Mahalo,
- Material - PETG
- Orientation - Vertical, I figured this would be the least amount of support material needed
- Settings - infill was adaptive cubic at 20% I think, but these things are fairly thin walled, so they’re mostly solid anyway, walls were 5 (again if I remember correctly), supports definitely (I did regular, but I think tree might be better), etc I did consider using a brim, but deliberately decided against it in the end.
- Working? Seems to be, but not really used in anger yet

Aloha,
Finally circled back to this and printed one (to make sure my settings were okay; I’ll print three more).
I have a Prusa XL with 5 tool-heads (extruders). I printed the upright out of blue PETG, and used PLA for the support interface (where the support meets the model. The supports are PETG until a couple of millimeters before the overhang.
My first attempt, I had some bed adhesion issues, but I sorted that out and the second time got this. It’s gorgeous, and because PETG and PLA don’t stick to one another, the supports basically just fell off. Had to use a dental tool to deal with the nut cavities, but it took less than a minute because again, the PLA didn’t stick to the PETG; the only reason there was any PLA left was friction with the walls.
