This Case is compatible with all toothbrushes in the protectiveclean series and have place for 2x W2 Optimal White Standard brush heads
Testet with Philips Sonicare Protectivclean 4500 and 5100
Nozzle: 0,4mm
Layer height: 0,2mm
Material: PLA, (PETG)
Support: For a better look of the curve, I used PETG support because it's very easy to remove. PLA support also works, if multi-material printing isn't available.

Without support the curves look bad with my Printer (Bambu Lab P1S).
