Anycubic Photon Mono X Build Plate Knob 5/16x1/2

thingiverse

Anycubic seems to be using a plastic for the knobs for both the build plate and vat that disintegrate over time from contact with resin. After my build plate knob shatter from tightening it like normal, I designed this knob to replace it. The normal bolt will slide right in and I cured it with the bolt in place. It's a bit larger than the original knob but I feel that it gives me better leverage to tighten down the plate. Included is a pre-supported knob. To get this to print successfully, I lowered my lift speed to 1 mm/s but you can probably get away with a faster lift speed with additional supports.
