Better wheel for Filament motion sensor.

The original wheel gave me some slips from time to time, so i started to think how to get better grip… and while printing some parts in TPU, it strikes me… A ring made in TPU, that holds on the encoder wheel. It should adapts better to grip filaments.
So far works awesome with PETG and PLA. ABS and ASA should work fine, but not tested. TPU is unknown, and dont know when will test it….
The encoder can be done in any hard filament. I recomend PETG…
The ring part, in TPU….

Modified the encoder wheel to use a TPU ring for better grip.
