CobbleBot Heatbed Table

Hi,
This is a heatbed holder to Cobblebot (or similar printer on 20mm profile). It fits to 2 mm thickness plate.

I've used:
- 20 x M5 Zinc Plated Tee nuts,
- 20 x M5 screws(8-10mm length, but You don't want with conical head) and nuts,
- 4 x M5 x 30mm(1.3/16 inch) screws and nuts,
and those 4 crazy yellow springs also from Aliexpress.

I've used also as heating source:
- a Silicone Heating Pad 350X350MM 800W from Aliexpress,
- 5,5m of 25mm(1 inch) thermally conductive tape.
