About this 3D model

I\'ve designed form for casting silicone button pad. They have exact same dimensions as buttons on monome. Now I have to do few more tries to avoid some errors but Itll be great. Designed in OpenSCAD and its parametrized, so you can generate as big form as you want :-) there is a room for LED inside button, just like in button pad from Sparkfun etc. It works, but the feel of pressing isn't same as on the monome, I\'ve updated design a little and it should be better now. If you have vacuum chamber you are lucky and you can have bubble free cast :-) I\'ve tried to embed some conductor when casting, but it wasn\'t great idea. Next time > cast and then glue the conductor :-) (in this case simple aluminium foil) >>> any tip for better and easier conductor?? Faceplate and PCB for this button pad is on the way too!! I\'m looking forward to print my own MONOME!!
