Some Logitech mice are known to develop scroll wheel issues over time. The pin/rod that rotates the scrolling mechanism inside gets worn out after a while and starts skipping. I used to buy replacement wheels online but they also tend to wear out eventually.
After having multiple replacements fail, I started Googling 3d printable replacement wheels and tried a few. Most of them worked, but they didn't look or feel like the original one in my hand.
In the end I came up with a simple solution to reuse the original scroll wheel by just replacing its problematic "pin" part. I'm very happy with the results, see the pictures for details and instructions.
I usually leave print settings as default in the slicer, but since these are tiny parts that needed to be precise and uniform I made some changes and used a small layer height,
Layer height: 0.05mm
First layer height: 0.05mm
Detect thin walls (not sure if it made any difference)
Slow print speed (20 to 30 mm/s)
I've not added any skirt or brim.
It's all printed with Esun PLA+ on a Prusa MK3S+
