For those that don’t have a 3D printer or don’t want to modify their existing buttons, I have an alternate option here.
I created a model based on @P53’s model. It’s just a 10-pack version of it for cheaper printing on Shapeways. I tried it out. Ten buttons (1 print) cost from $6-12 depending on the finish and color you choose. I made all the options available. I only personally tried out the white premium plastic and it came out really nice.
Not sure exactly if this breaks any rules. Mods, let me know if it does or delete. Just trying to offer an option for some until there’s an official offering.
