Third point of support
thingiverse
I have upgraded my heatbed by installing holes at each corner for effortless support - three key points now facilitate easy leveling. Conveniently, the center supports do not require fastening. Two essential features are incorporated at either side to secure the nut, ensuring smooth adjustment during setup. This new design aligns perfectly with standard Prusa bed holders featuring three sliding bearings. Note that some images may display four bearings, but rest assured this remains unchanged for our purpose. For the second version, initial tests showed the first prototype was undersized; hence, I expanded it slightly - a welcome upgrade now providing an optimal fit.
