Oral-B Brush Holder 3-10 (Parametric)

I needed a new holder for the Oral-B brushes.

This is attached with double-sided tape on the back in a .6mm offset surface.

There's a .2mm offset in the front above each brush head, i.e. a dedicated space a label, if you want to.

Pre-made sizes

If all you need is a brush holder, choose one of the sizes (3 - 10) and download that.

Pro's & Cons with my chosen print direction

I've chosen to chamfer the outside corner so it could be printed at a 45° angle. This produces a really good print because there was no need for a brim around each hole, which was a pain to remove on the first test-print. And because I wanted to release this publicly, I didn't want to have to suggest using a painful-to-remove brim just to make sure that it wouldn't curl on some plates or with certain filaments. When standing on the edge like this, a few small supports are needed however, in order to support the .6mm wide overhang that stretches the entire length of the offset in the back. It's not pretty I guess, but it will never be seen and prints just fine on any modern printer.

However, since I've released the .f3d file, you could remove the chamfer on the back if you want, and print it with the bottom down, but I'd recommend a brim if you do, and you'll need some skill with the deburr tool to get it looking well. I am not good with the deburr tool… 

Parametric file

If you want to have a bigger one, download the included .f3d file, open it in Fusion and edit the NumberOfHoles parameter. The design is fully parametric so the rest of the model will adapt.
NOTE: If you go down to 2 or less, some features can fail, but they are easily fixable.

Recommended print settings

• Walls: 2
• Support (tree/manual, Slim)
• Infill: 10% gyroid
• Paint supports in three places at the top of the offset area in the back. The 3mf file has this support painted in already.

I used a White matte PLA from PrintOnion (NOT an affiliate link) for this.
