This is a simple paint brush or pen or whatever-will-fit holder. It measures 80 x 80 x 160 and has 22 10mm holes and 4 20mm holes for holding anything you need to stand upright.

You can use whatever print settings you prefer, but I would suggest a standard .4mm nozzle size, .2mm layer height, three walls on all sides, and 15% cubic or gyroid infill. On a P1P at the standard speed it should take approximately 4 hours to print.
