Description
A Multi-Use Case can't fit every situation. Because of this, I designed this toothbrush travel case in the same style as my Multi-Use Case. I have designed it to be as compact as possible, but still fit as many styles of toothbrushes as possible. I tested these with 5 kids on a 7 day trip. Not only did these cases survive the abuse, but they performed wonderfully!
Use a section of 1.75mm filament inside the hinge to connect the lid to the base. Depending on your printer/setup, this hole maybe be on the tight side or a bit loose. If tight, drilling out the hole may help. If it is slightly oversized, I suggest melting the end of the filament piece with a soldering iron or lighter.
Both pieces can be printed with 3 perimeters and 0% infill. Using these settings, all walls of the case will be solid. The only gaps left by using 0% infill will be very small in the angled sections of the hinges. The combined print time was 47 minutes for me.
PLA has worked for most users. However, PETG may be a better option if you have any issues with the clasp breaking.
The following filaments were used in the pictures above:
