#video of #Evan-and-Katelyn #manufacturing #concrete keycaps for a custom keyboard with PVA glue replacing some of the water in the cement (like a quarter or half or something), using personal vibrators to get the mix down into the keycap molds where they’re overmolding keycap stems made with #3D-printing. Also they tried adding 3% chopped fiberglass to their concrete mix, which is totally going to fail. They also tried adding more sand. To suppress bubbles, they loaded the keycaps into a pressure pot to cure. The fiberglass concrete wasn’t sandable, breaking apart. The PVA concrete felt “super hard and dense”. They also made the outside of the case out of concrete. It weighs three pounds, and the wrist rest another 1.7.
