printed at 0.185 on my MPSM with 100% infill (lines), 50mm/s, Sunlu PLA +. Took about 4 hours for the main part, 2 for the thread and 30 mins for the protector. This thing is solid! I may print the thread again slighty scaled up to make it more snug, but it seems to work ok. I can screw it down pretty hard before it begins to warp.
