I found the regular feet of my Logitech MX Keys too sticky (I move the keyboard around a lot).

That's why I printed the back raisers from Thingiverse (thing: 4877517) but did not find any raiser for the front - so I made my own.

If you want to avoid supports, you can print the raisers standing upright.
(Good bed adheasion required /  the smaller the layer hight, the better the quality)

For printing flat, I would recommend supports.

Added a +5mm height version, which should bring the front of the keyboard to the same height as the back (if you don't use the back raisers).

Added a +5mm height version for the new MX Keys S (double sided tape needed).
