Custom 12V Heater for UM2 Clone

I've finaly made it!
This is my custom heater for my 12V powered Ultimaker 2 clone.
It's based on original Ultimaker 2 heater layout. I've laser cut it of 2mm PA6 aluminum plate. I've drilled M3 screws sockets with 6mm drill bit.
It has 200mm x 200mm @12V silicone heater glued to the bottom of plate and 4mm glass on top. The glass clips are the same as on original UM2
