Anet A8 E3Dv6 carriage

I designed this carriage because I could'nt find one that I liked. I don't think the material type matters that much, but because PET is stiffer and more heat resistant I went with that. You'll need some screws of your own, you can't reuse the Anet A8 ones for as far is I know. I designed this to work with various M3 and M4 shoulder bolts. There is only one size for the sensor (12mm) because that's what I have. If there is any interest in a 16mm version let me know, I'll try to make that too. It
