To solve the problem of the paint peeling off the plastic clips of the sound color, I originally used spray paint to solve it, but the paint would still peel off after a long time of use. So I used food-grade silicone to mold the clips and filled them completely with UV-cured glue. I imitated the independent keys of propen3 and cut some cotton swabs as keys. This inspiration actually originated from a user on Twitter who used a 3D printed model. He used very small screws. As an independent key.I think in the future when I have propen3, I should also make a separate key to solve the problem that the original key is prone to damage.By the way, my pen cap was made by paying someone to use 3D printing, and the material is PA12
