A print-in-place travel case for 2/4/6 Oral-B toothbrush heads (Vitality/Pro/Smart/…, NOT iO/Pulsonic), including 2/4/6 stands. Before that we just carefully placed them upright somewhere, but they often fell over. I had several iterations of those stand pegs (including one with the actual profile), but decided for this sleek design to use a tad less space, but even more to allow easier cleaning. The 4 brush model is updated from the version shown in the photos to have shorter, more rigid vents (like the 6 brush version).

The 6-brush-version does not fit on my Prusa Mini - it's 19.3 cm long.

Print-in-place, no supports, 0.4mm nozzle, 0.2mm layer height is fine on my Prusa Mini with recycled PLA.

Edit: Added 2 brush and 6 brush version.

Edit 2022-10-10: I added files with wider clearance for the hinges ("-widetol" files) as well as a test piece ("-test") to print out and check if the normal files will work. To check if the wider tolerance version works for your printer you can cut the model in the slicer to make a similar test piece yourself.
