Actually was the paint thinner. I used a paint pen (those with a ball inside) and thinner to clean some mistakes in the coating. All the outer layer was eaten by that combination, in conclusion: I have now exclusive very tiny mate buttons that do not hold inside the case (the thin ring was eaten too)
For 5 bucks I am guessing that is cheaper than getting 4 screws shipped from USA. What you need is M1.5 x 3 mm (head diameter 3.6 mm <- not that common in those packs).
So actually we don’t have any extra buttons to sell… yet…
Funny story, the minimum order quantity for buttons is 10,000 units from our factory. But only need 750 gold buttons for the arduventure.
So we’re about to have way too many gold plastic buttons, let me talk to the factory what we can do to sell them. Gold only but yeah you can paint them.
I can see that, but creating them from scratch as you did is harder. I just copied the original ones. It is strange that the lip in the directional buttons is thinner than the round ones.
I am just trying to find a reliable way to create the “pointy” bump to press the button dome
