This is meant as a replacement part for the bottom negative stage plate for LPL 4500/7450 series enlargers. If you're somehow missing yours or it broke, this should be a direct drop-in replacement.
You should print it in a black (preferable matte) filament to reduce flaring. PLA is fine unless you plan on doing extremely long exposures with your enlarger, then switch to PETG or ASA/ABS to survive the heat better.
The author marked this model as their own original creation.
