I could not find any beard beads on the internet, so I decided to make my own!

File includes one beard bead with Norse-inspired knot all around.
Printed using supports oriented with hole vertically (not like in the .stl file). Although removing supports was quite painful and irritating, it came out well (I didn't try printing without supports).

The knot is not absolutely perfect, as you might realise, because it repeats three times one knot structure which doesn't have compatible ends. But, nobody's gonna notice that while you wear them, I believe. :D

Printing settings:
Printed on Prusa MK3S using PLA named Graphite Black from Filament PM. Resolution 0.1mm (0.4 mm nozzle), with supports (works also without supports), no raft, 15 % infill, 3 perimeters.
