Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:3829065.
We really liked the design by Thingiverse user gamingoodz but we wanted to use some old toothbrushes to clean the bicycle chain, so we modeled this. It should fit most normal toothbrush models around and uses two M3 screws to keep the cover in place.
The things you need are:
- 2 x M3 screws (we made the holes 16 mm deep because we had M3x16 screws at home, but even M3x8 should work just fine.
- 3 old toothbrushes.
- Around 7 meters of filament.
Prints without supports.
UPDATES-2022 - 01 - 15: Thanks to Thingiverse user @draws_with_kitties we realized that this actually looks like a creature eating up the bike chain. So we decided to add some fun to it :)
We also made a parametric version of this, so you can modify it to fit the brush heads you are going to use! You just need to adjust some parameters on Fusion 360, and the dimensions will adjust automatically. If you don't want to adjust the CAD file, the STLs available will fit most standard toothbrushes ;)
Please let us know if you print this! we would love to see your prints in action. And if you have any suggestions, let us know in the comments or with a message ;)
