I'm not sure I understand your question about wanting money. As much as it would be great to give them away for free, the reality is that it cost us money to produce them and it will cost us money to ship them. We're running this campaign in order to simplify the logistics of offering our extra keys to other people.
Regarding custom key caps, another commentator was correct in saying that we're milling entirely custom shapes from raw materials (aluminum in our case).
As for the circulation of Cherry MX Reds, I could only find them available in small quantities for what seemed to be very high prices, when I could find them in stock at all. The Cherry MX is a great line of switches, but Cherry is doing a poor job of helping people (well, me at least) make new products.
I haven't noticed the Matias switches being super wobbly, but I also don't have a full keyboard built yet. I'll keep an eye out for this.
And the reason I'm cynical about it is that they story they offer doesn't seem to make sense to anyone who has purchased key switches for projects.
So lets break it down. $50 donation gets you 150 switches, they are looking to raise $1000. That is twenty $50 chunks, or 3,000 switches. So what they are really saying is that our vendor has a minimum order quantity (MOQ) of 3,000 switches, and if you all buy some, together we'll get switches and you'll get switches. That at least would be an honest narrative. And hey its helping the Open Steno project so its got that going for it.
No two makes of Alps keyboard have ever used the same stabilizers I think. Designing that I think would be a pretty big job and Matias has a standard layout for their own boards already (as long as you use Macs).
Might.
Why do you want money again?
The claim that it's easier to get Custom Key Caps for these is an absolute joke. There is very little available in the market for Alps style keycaps vs Cherry MX which is ubiquitous. Injection molding shops would have to have tooling available to make these keycaps. Most of them don't. That's what makes getting custom keys easy or hard, not the mounting shape. I don't even think you can get them in PBT anymore unless you pop them off an SGI Granite keyboard or older Apple keyboards (or with a Japanese layout).
Cherry MX Reds are also not out of wide circulation at all. Reds and Browns are their most popular switch right now! These comparisons are totally disingenuous.
Not to mention Matias switches are super wobbly...Have fun doing those sticker mods.
