Travel Cap for Philips Sonicare electric toothbrush

This is a minimalist travel cap for the Philips Sonicare toothbrushes we use in our household. The cap fits onto the toothbrush with similar dimensions as an actual brush head, with a friction fit on to tip. When fully installed, the force of any knocks on the head of the brush should be carried by the "shoulders" of the toothbrush instead of the more fragile tip. The cap also covers the power button to prevent accidental power on within luggage.

Note: the cap fits only one way, oriented so that the extended portion covers the power button on the "front" of the brush.

Compatibility

Beware! From reading the descriptions and testing other 3d printed cases for these brushes, it's clear that there are a huge number of models over the years, with subtle changes to shape and size.

I have printed this model on a Prusa Mk3s in PLA and PETG and the friction fit and sizing came out perfectly for the only two models of toothbrush I have available for test.

Known compatible models:

• HX939W

• HX993W

Frankly: I don't know whether this model will work for your toothbrush, and I'd love to hear back whether it works for you! Please be careful in testing this model. Toothbrush sizes may vary even within a single model, and printer tolerances and accuracy definitely vary. Don't force your toothbrush and break it!

Printing

This has been easy to print with the following settings:

• Printer: Prusa Mk3s

• Filament: PLA or PETG, standard profiles

• 0.15mm layer height ("0.15mm QUALITY" in PrusaSlicer)
