There was a request for a blank version of my previous model, so here it is

I've printed it in PLA and painted it with a wear resistant spray-paint, but if you don't have this kind of paint, just print it using PETG, or if you have an enclosed printer, ABS

When slicing, BE SURE that the final print will be watertight (use 4+ walls and 4+ bottom and 4+ top layers) if you don't plan to get it painted. When exposed, the print will trap water inside it's internal structure, and that will weaken the internal structure, making it soft and brittle, I've lost several prints for this reason.

However, if you just print it to be indoors, then it won't matter
