worked great. printed in basic PLA with a custom filament preset there's a strange gap between the supports and the flat part of the print so the bottom printed a little funky. my calipers are reading about 8.3mm from the comb to the blade on the '6mm' guard. so the '6mm' is actually around an 8.3mm could also use a lip to easily remove the guard from the clippers. I made a few mods like fixing the height, adding the lip and widening the combs... will see how it turns out.
