A knob design to make it easier to rotate the knob on my Anycubic Mega SE.
The original knob just feels super smooth and doesnt allow for much grip, this design aims to fix that.

The finger indent ended up being mostly useless, which is why I have included variations with flat tops, bottoms and markers.

Will probably work to replace other knobs as well.

Even after measuring the original part and designing with those dimensions I had to increase the scale of the model to 102%. The should make it pressure fit snugly.

If you find yourself not being able to push it all the way in, lift up the knob slightly and use something thin to block the rotary switch. You should now be able to push it in all the way, without the switch moving along. (Check the last photo)
