Print Settings: 

• 0.4 Nozzle

• 0.2mm Layer Height

• 40% -60% Infill of choice 

• 5 Perimeters

• Printed fine without any supports on MK4. I used Prusament filaments.

Materials and Tolerances:

• PLA with T-0.1mm pretty much screwed in without any post processing while

• PETG-CF needed light sanding. That's why I'm attaching 2 options for download with 0.1mm and 0.2mm tolerance between clamp and the pin thread. I would say - if you have some sanding paper and small round file (2mm) to clean between threads go for 0.1mm model and make it as tight as you want. Otherwise 0.2mm option might be easier and require no post processing (Tested). 

• PC I test printed one Clamp Frame sideways, - it works as in the photo of description.

Tips:

• To Mount Bottom-Ends I suggest rotating handle clockwise all the way till Pin pushes itself in.

• To Dismount I suggest to rotating handle counter clockwise all the way till Pin unclips itself.
