Knobs with Caps

3D model description

Yet another bunch of knobs for metric 6 (M6) and metric 8 (M8) bolts and nuts. Use caps with holes for nuts and others for bolts.

The housing for the hex head of bolt and nut is a bit tight by purpose. Do not hammer them into these printed parts. Instead, use the method of fastening them in opposite direction. This will pull them into its places. I have shown this method in an animated gif below. Caps are also coming little tight. Use a vice to push them into top openings. I used PETG on Prusa I3 Mk3 and utilised Ultimaker Cura 3.3.1 with 0 (zero) Horizontal Expansion setting. If you encounter loose fits, then you might consider to try Ultimaker Cura 3.3.1.

Happy printings.
