Hey all,

As you can see on picture, I designed simple key cap. I would recommend you to use my presliced G-codes for PLA / PETG caps. When i printed these caps I decided to try out fuzzy skin feautere in PrusaSlicer and I was quite suprised how good it is look (presliced G-codes are also attached). However you can print that in standard way with smooth surface. 

Caps fits to my keys without problem, but in any cases you can scale up/down them - you can use new great measurement tool feature in PrusaSlicer
