I don't know if this offer is still open, but I'd like to be in it if it is. What I need are enough Cherry MX relegendable keycaps to replace all the keys on a FILCO 104-key Blue Cherry MX NKRO keyboard. I tried looking for Cherry MX relegendable keycaps on Hooleon.COM, but the sample they sent me is 8mm tall with a grey base, and the relegendable area is only on the top (the front is not relegendable). In addition, the keytop is flat, which means that replacing all the keys on the FILCO keyboard with them would eliminate the DCS profile that the original FILCO keys presented.
Each Cherry MX relegendable keycap from Hooleon.COM costs USD 2·75, which would mean that a full 104-key replacement costs at least USD 286·00 (and that's assuming the larger-sized relegendable keys cost the same as the 1x1-size relegendable keys, which I'm sure they don't). I'm not sure if Hooleon.COM even has any compatible, larger-sized relegendable keys to sell.
The circumstances that led me to search for replacement keys for my FILCO keyboard are funny, but also tragic. I had noticed that the coating on some of my FILCO keys had started to wear off, and reading threads in this forum convinced me that the keys would be better off with no coating at all. I pulled out all of the keys (including the red ESC key) and put them in a laundry bag and then put the laundry bag in the dishwasher. Big mistake: the dishwasher didn't do anything to remove the coating on the keys (keys from a $10 rubber dome keyboard did not manifest this problem, and the FILCO red ESC key was unaffected as well), and instead left translucent white splotches all over them. I have subsequently tried cleaning the keys by hand with an old rag and cream cleanser. I can get the keys buffed to a smooth shine with this method, but it is a terrible strain on the fingers and there are 104 keys that need cleaning. I then tried scrubbing some keys with a green ScotchBrite scourer (the blue one didn't have an effect). The scrubbed keys lost their coating and white splotches, but gained several scratches in the process, and the effort involved is only slightly less than that of the cream cleanser method. I have also tried washing some of the keys in a hot water bath using laundry soaker enzyme powder, with the water being too hot to touch but below boiling point. No good. The keys in the hot water bath retained most of their coating and white splotches, and became warped by the heat to boot.
Rather than buff every single key, I thought of getting relegendable keycaps instead. They don't have any coating. They can be colour-coded. They can have any font your printer can print. What's there not to like about them, aside from the cost? The DCS-profile Cherry MX relegendable keys from Signature Plastics sounds like the answer to all my problems. After this, all I will have to do is get rubber o-rings for each key and a FlexSkin keyboard protector that fits the FILCO's 104-key layout, and I will presumably have a fully-upgraded keyboard!
