Heated bed frame

I designed this frame while building the Core A8 Slim (https://www.thingiverse.com/thing:3588785). The z-carriage didn't work for my 410x410 bed because it is to big and heavy so the rods and clamps started to flex. This setup is way more stable and flexible. Using larger tubes you can fit even larger beds then my 410x410, but also smaller and odd sizes (310x310 or 300x600) should be possible.
