This is a kit I made for my keyboard ZSA Voyager (https://www.zsa.io/voyager) for 3 combined purposes:
No gluing, no screwing. The keyboard remains in place thanks to the magnetic feet of the keyboard, finding their place in the holes in the support.
If your printer has a smooth and clean bed, you should print with the upper side of the support laying on the bed. Otherwise, print with the lower surface down, but make sure the top surface remains horizontal to avoid unaesthetic steps or brittle edges on the top surface in contact with your hands (be aware this will require quite a lot of support material).
This version fulfills my needs (I have been typing with it for one month full time now), but let me know in the comments if you have any remark or suggestions for improvement.
By the way, great keyboard!
