My first run of keycap casting was a partial success, partial failure. I forgot my pointy tool to get the air out of the keycap stems so there was a big bubble instead of a stem. Other than that they formed really nicely! Some very minimal bubbles on the outer edge of the top but the form and texture look great.
Well that's a dead mould, and the last keycap didn't survive either :(
The silicone gets brittle over time. Depending on the mould, people say you can get anywhere between 10 and 120 casts from it (for something with features this small it'll be on the low end). It looks like this one only managed somewhere around 16 :(
Basically, casting an entire keyboard worth of caps is a bad idea. But I'm doing it anyway!
The full keyboard is getting there though! Some of the caps are a little loose so I had to put some tape underneath. It makes the fit of the stem a little tighter (hopefully without breaking the stem)
It's very tedious with only two moulds, and I'm out of silicone to make more. This is definitely making me want to get a resin 3D printer to make some custom shaped ones.
