Here's a basic keycap set I made for my K95, but will likely be compatible with any Cherry MX based key switch. Includes all keycap sizes as individual files - feel free to mix and match to create your own colour set.
The keys feel good but require increased accuracy due to less forgiveness in the spacing between each key. Mainly for looks, won't make you a better typist ;)
Printed in PLA 0.4 nozzle at 0.15mm in the pictures. The white works really well for the LEDs (shame half of mine are busted after a water spillage).
Original design based off https://www.printables.com/model/109679-cherry-mx-low-profile-keycap but modified to include a thicker “key” portion as to not show the keycap stem through the key itself when backlit. Also lengthened the “skirt” around the key to better hide the key switches (and crumbs) of the front row.
