This is a simple and functional holder designed specifically for Oral-B iO toothbrush heads, with 4 dedicated slots to keep them neatly organized and separated.

The model was printed using 15% infill in TPU, giving it a slight flexibility that helps with grip and durability, especially in a bathroom environment. That said, it can also be printed in PLA without any issues if you prefer a more rigid result.

For best surface quality, adaptive layer height is recommended, especially to better define the curved tips of the holder.

If you use the provided 3MF file, adaptive layers are already configured.

Alternatively, the model can also be printed with a fixed 0.2 mm layer height with good results.

No supports are required, making it a very straightforward print.

Print time is approximately 52 minutes, with a material usage of about 10.5 grams of filament.

⚠️ Do not scale the model. The dimensions are calibrated to properly fit and securely hold Oral-B iO toothbrush heads.

The design is compact and minimal, ideal for countertops or shelves, and keeps the toothbrush heads elevated and separated for better hygiene.
