Holds up to 6 interdental toothbrushes from DM. The hole is tapered in one direction and holds the toothbrushes securely inside with just friction. The bristly part of the toothbrush is well protected and should have enough clearance to not have to touch inside walls of the box.
Comes in two parts, lid is optional.
There is no closing mechanism for the lid, only friction keeps it in place. The lid is 100um larger than the box. This is a margin that works well for my printer, your experience may vary. It certainly may become worn out over time and hold less securely.
The author marked this model as their own original creation.
