Hi JamsterJules, That is very kind of you to say, thank you very much! Yes I do calculate the tolerances for the parts. Depending on the mechanism and the color of PLA I use, I allow .1mm clearances for press fit, and .2mm clearances for slip fit. Thank you very much again! Greg
Hi Mskvaer, The axles in this video were 3D printed in Ultimaker Black PLA including the threads. Depending on the color I 3D print them, most often the threads work fine right off the build plate, but I times I use a tap and die to clean them if they're too tight. Greg
