I recently started casting keycaps as a quarantine hobby.
I’m making one a day.
I’m pleasantly surprised the quality of the mold registration. It captured the matte texture on the tops of the keys while keeping the sides smooth and shiny.
The keycaps are susceptible to giant air bubbles. I’m taping the mold to release trapped air but I might purchase a pressure pot in the future.
Once I master the fundamentals, I’ll attempt to make embeded keys like Jelly Key.
