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 6-brush-version does not fit on a Mini - it's 19.3 cm long.
Print-in-place, no assembly, no supports, 0.4mm nozzle, 0.2mm layer height works fine.
I added a test piece on the 4th plate to test it the tolerance works for for printer/filament/settings. If the hinges don't get free, try a lower flow ratio (in the filament settings), or if the hinges are too loose, try higher. Also adjusting the X-Y contour compensation might help.
