Bed Isolation Holder

Got an Anet A8 and tried to cut down on bed heating time so I isolated the bed from the bottom with some leftover cork (glued 3 pieces together to get a 3mm mat).

I designed and printed this frame to press the cork against the heated bed.
I used shorter springs, as the frame needs a little space.

You need to print 4 corners and 4 sides, which just snap into each other.

Still working on it and testing it out.
