Build Plate Screw Lock

thingiverse

This model requires careful preparation before printing; don't just open and print it. It is a mock-up design that needs modification in your CAD software. Delete the three set screws and three bottom wing nuts visible when viewing the model from below. Then, adjust the circular wing nut retainers' size and position to fit your specific build plate leveling screws. For installation: Purchase three appropriately sized wing nuts and three set screws. Move your extruder away from the build plate, remove the thumbscrews used for leveling, insert the wing nut retainers into the frame's holes, pass the leveling screws through these retainers, thread the wing nuts onto the screws, adjust the build plate to level it, and finally, tighten the set screws - hand-tight initially followed by an additional 1/8th turn for secure locking.
