The purpose of this model is to hold 2 brush heads of an Oral-B toothbrush. It has a cover that will print with it, with the purpose of blocking them from getting sprayed with hairspray or any types of power, there are vent holes in the back of the cover that should match the same pattern that is on the stand.
I recommend using the brim with the cover since mine was curling the edges up while printing, the edges have a 0.5mm chamfer, same with the stand if it ends up curling for you.
