I have a custom 3d printer that I'm looking to upgrade with the 300x300mm high temperature heated bed, but I need to figure out a way to mount it to my printer. To give a little background. My printer is a custom design from a class I took that was originally a combination 3d printer/CNC router. As part of the CNC router design, the print bed is a glass plate on an MDF waste board. No heated bed. However, I don't use the router function and would much rather have a heated bed. Only problem is I can't find a support plate to use for the 300x300mm high temperature heated bed so I can mount it to my existing frame. Has anyone else installed this heated bed and have any recommendations for a support plate or other mounting method?
