Large M6, M8 Clamp Knobs

Clamp knobs in both M6 and M8 sizes. Designed to print without supports, I am successful in printing these in PLA without supports on a Creality CR10 printer.

These knobs are large with an outside diameter of 48mm.

Updated: Added an 8mm version where the nut cavity is 1mm smaller. This just fits the nuts I have, but have to tap them in with a small hammer.
