I've been printing the Honeycomb storage wall and creating some of my own attachments. I prefer creating attachments that use the m3 piece to attach to the wall. I took the profile from HAMMER_T's original mounting clip and just shortened it since I didn't need the actual clip. I added a countersunk hole for the M3 screw and it works great.
The author remixed this model.
Removed the retention portion and added countersunk hole for an M3 screw to attach to the honeycomb storage wall.
