This print allows you to put cherry profile keycaps onto a membrane keyboard. There are two files, one with and one without the “nub”. The mechanical keyboard I have, Razer Ornata Chroma, has a mechanical aspect to it, so the nub is required to actuate it and get a “click” from a traditional membrane keyboard. If you dont need or want it, print without it.
The author remixed this model.
I made the adapter shorter so it doesnt stick out so far, as well as removed the 3d printed keycap so any keycap could be added instead.
