Great results with Bambu PETG-HF. Good print quality and the lids easily snap to the containers, yet stay firmly in place. Remember to print the matching rear container too. All together, they hold approx 320 g of dry 3mm silica beads.

Great quality and fit. The magnets are easy to install but stay in place without any glue.

Great results with P2S loaded with Bambu PLA Basic. Numbers on both sides are very clear with 0.4 mm nozzle. Scaled both parts in Z-direction to 105% as suggested by others and the magnets nicely sit flush with the surface.
