Kossel mini heated bed support

This is a small support set for my heated bed.
This heated bed consists of a kapton heater glued to a 2mm aluminium plate. This plate lays on a 1mm cardboard for insulation.

I wanted to keep the removable borosilicate glass, so i made his design. It's the original design that came with my printer, but i made it deeper (7mm instead of 4) and thinner (not to lose any height).

I printed it with _xt from Colorfabb because it's really tough and can handle the temperatures i use for my prints but ABS might be a better choice for a larger set of temperatures.
