This is a toothbrush cover that includes a case and a top that slides close and snaps in place.
Printed with a skirt outline on a PEI print surface. I had to remove some extra plastic from the grooves on the case cover slots but after that, it slides in without any issue and locks in place.
Version 2 has larger ventilation holes on the base and a cover with a notch for easier removal of the lid.
The lid will work printed at a 0.2mm layer height but fits just slightly better printed at a 0.1mm height.
