DXF of heatmat

[kse]

I'm completely annoyed by that extreme long heatup times that are caused by that stupid low powered dc heatbed.
I want to replace it with an AC 700w silicon heater mat and a SSR i would ask keenovo to custom manufacture it.

Is there a DXF / technical drawing of the original heater mat available? i know the mat has some holes for screws in it.

does someone has an old broken heatmat or a spare in reach and can take measurements?
