Printed on my Bambulab X1C.
Print the flat face with the hole for the USB port down
Enable supports on build plate only, snug standard supports to help the hexagon supports should be fine.
I printed on .24mm layer quality because it is hidden but it will work at any quality. I haven't had issue with the HSW hexagons not fitting.
The author remixed this model.
I added correctly spaced honeycomb inserts for the Honeycomb storage wall found at the link below. The screw holes were covered up from the original model, but it is otherwise unchanged. The inserts are spaced 4 sections apart (there is a gap of 2 blanks between the inserts)
