I decided to re design this iconic hanger. I created two versions considering different types of things, so you can print some copies and install them using screws or foam tape.
I printed the prototypes using PLA with 15% for the Infill. 0.2 mm height but you can use 0.28 mm too. 0.4 mm nozzle. Pla or PLA+ should be enough. Just play with the Infill for more resistance. I included the STEP file in case you want to edit something. I highly recommend using colors for the 3d prints. ;)
