This is a model where you can print people's names (or really just anything), and assemble these on any keyboard switch by placing the keyboard switch inside the “stick” thingy where the switches will clip tightly in place.
You do need to buy the keyboard switches seperately. However, all the switches I tested fit and clip nicely into the design file I made. (I tested ones from TCL, Cherry Blues and Reds, and some off-brand blue switches, all of them clipped tightly into the contraption)
After you assemble them, it is very stress-relieving and fun to press. A great little present to give to your friends or family members, or just to keep to yourself.
These keycaps, if required, can also be used on keyboards, and they fit nicely onto any standard mechanical keyboard with standard switches.
(The keycaps are 8.88mm high without the letters, with the letters extending upwards from 8.88mm to 9.28mm (2 layers on 0.2mm layer height)
Enjoy!
