MK3 Reprap aluminum Round 265mm Heatbed

This is not intended to be printed!

It's only a 3D shape of this type of heatbed:

You can easily find other sellers on ebay with the same item, I'm not advertising, just pointing an example.

It's a 265mm round heatbed, with a thickness of 3mm aluminium, to be used with 12 or 24v.
I bought one, and needed to design it in order to make the correct parts to make it fit on my delta printer.

So I just place it here, to help anyone wanting to use it
