Modular plate holding rack. Print at least 4 pieces and glue together for stability. Add as many as you like. I used PrusaSlicers features to print at a high layer height and no top layers and 10% honeycomb infill until the surface below the pegs to decrease plastic used and lower print time. Also for the aesthetic. No supports are needed.

Print instructions

Print as oriented. No supports needed. Gcode and 3Mf for stock MK3S included will produce the print in the pictures.

Update : STL file updated with correct orientation. Print laying flat on back with prongs facing upwards.
