A very simple, relatively fast to print wrist rest for 40% keyboards.
All the ones that I found online were designed with the print lines on the top, which I found quite ugly. So this beautiful little fella was born. Nice side effect: You can wrap the wristrest on top of the keyboard for easy transportation.
And the best: The MK3S+ nicely fits it as one single print.
