It printed well enough for my liking after like 4 tries. At first, the same part (axle) snapped just like the original one did - reinforced it a bit and tried different printing settings - this one works well for my liking and is strong enough.

The easiest way for me to get the wheel out of the supports was just twisting it in one direction or the other, like you would normally use the mouse scroll wheel. (Just make sure your plate is cooled down)

I've recommend using support with interface - different material if you're printing wheel with PLA, then PETG as interface and vice versa.

Mouse works! Couldn’t be bothered to clean it up for the pictures—sorry for the nasty visuals in advance.

Don’t forget to put the rubber on the wheel before assembling the mouse!

I did it with a 0.4 nozzle—probably 0.2 would come out neater?? Most probably.
