k40 door backplate
thingiverse
This plate is designed to seal the gap, ensuring that laser beams remain contained within their enclosure. To secure it in place, I employed a door handle from Thingiverse (https://www.thingiverse.com/thing:36465). Two holes must be drilled into the metal door to accommodate M3 screws and nuts. For this setup, I opted for 20mm long M3 screws.
