I wasn't happy with existing bit holders, so i made this!
Orient as shown in the picture, slice however you like (PLA, 3 perimeters and 0.2mm layers worked for me)
Does not require supports
The fit into the wall inserts is quite tight; this is intentional to provide a secure fit.
The author remixed this model.
The base HSW system does not have a holder for ΒΌ inch bits. I designed one.
