Thumbwheel Anet A8

Thumbwheel i searched for Anet A8 returned wheels which are too thick which causes movement issues for Y carriage or is too big in dia causing issues with frames.

Thumbwheel uploaded is just 4 mm thick sturdy enough to use and have rounded edges which goes easy with ur thumb.
Can slide in between frames without any issues
M3 nut fits in but would advice to glue it in to make even more rellable
