.scad based heatbed & glass clamp that can be adjusted to your setup to provide an exact and tight fit. The .stl provided makes some heavy assumptions in your setup, so you'll have to adjust the radius and height of each of the layers (glass, heatbed, cork insulation layer, and bottom frame) to get a correct clamp. Adjust the path of the dxf before printing (remove any path component if you use the dxf provided) Print this in ABS since it'll be exposed to high temperatures. Tested to hold tight even with a print bed temperature of 130 celsius. Best printability if rotated by 90 degrees.
