You can use it for your Gridfinity system to organize your big spools.

It‘s printed in two different parts (baseplate and 4 pins) so you can insert the pins into the baseplates. Advantage: if one breaks you just have to print a new pin and not the whole plate.

I printed both with PLA, 8% infill and the pins with brim of 5-7 mm (dependent on grip of your plate).
