I wasn't happy with existing HSW bit holders, so i designed my own…
That one didn't work well for long bits, so I made this!
Orient as shown in the picture and slice however you like
(PLA, 20% infill, 3 perimeters and 0.2mm layer height worked for me).
The holder fits securely into an empty insert, found here:

The author remixed this model.
The base Honeycomb Storage Wall system does not include bit holders of any kind; I designed this one that mounts like a hook.
