Just a simple ring design to mark individual Philips Sonicare brushes. Quick to print and reusable. Mine have been in use for some weeks now and so far there are no problems or collisions with the rest of the toothbrush.

How to install:

Slide the ring from the brush end down and push evenly until the hooks align along the bases edge (see pictures).

How to print:

Due to the very small contact surface using a raft is highly recommended. When find the hooks snapping of or layers seperating while installing the ring, try printing it again with with higher temperature (e.g. the purple ones were pinted 10 °C higher than I usually print fillamentum PLAs).

Material:

The markers you see were printed in PLA. I tried one in PETG, but it ended up being brittle because my filament was to moist. So try to use dry filaments when printing with humidity-sensitive materials.
