So you've got an old drive belt in your projector, cassette player, turntable, old device that uses drive belts and its failed.
Make a new one.
Things to consider:
Filament - Ninjaflex, and other flexible filaments, might be ideal for this.
The cross sectional number of steps, if its something like 9 or 12, will give you a flat base on the printbed to build on.
- Making the belt smaller than needed might be required for your filament. Some filaments stretch more than others. Luckily you can print them until you find a solution because, well you know... you've got access to a 3D printer...
This is possibly the simplest customiser I've ever made but this sure is useful.
Resolution and layer height will depend on Filament selection. You'll need to experiment to find the right mix of layer height for your drive belt thickness. Some will want many thin layers and others will prefer a few thick layers and a more rope like final result, which might be stronger.
