Darkroom Paper Burning Tool

thingiverse

A paper burning tool heavily inspired from an old Romanian darkroom book and some pictures from the Way Beyond Monochrome book. Drill two 4cm holes (one close to edge, and one in the center) of ita A3ish piece of cardboard. FIxthe two discs to the cardboard with an M4 screw (or butterfly nut) and bolt. Then they can freely rotate and together, they can make all sorts of different shapes for burning in prints. Have a look at the pictures for any clarifications. Paint top in orange or red, so that you can see what you're doing without sending back light into the room. Bottom either painted matte black or left as-is if printed in black. Prints in anything black, most likely - I printed with a 0.6n nozzle, 0.2 layer. Needs to be perfectly opaque.
