Precision thumbwheel for CTC A10s

Hello, this is precision thumbweel for CTC A10s (CR10 clone)

This wheel was inspired by [ idig3d's CR-10 Precision Thumbdial ](https://www.thingiverse.com/thing:2603493 "You can find it here")

I tried this model but it would not fit. CTC uses slightly different original dial
Oiginal has 18 small protrusions and overall diameter is 18.3mm.
I designed my own thumbwheel for this printer.

If You are not sure please print just middle part first and test.
