About this 3D model
The hexagons on the top are sized so that V6 nozzles can lightly screw into them. The 2 hangers on the back are spaced so that a 7mm wrench can be hanged from them, for changing nozzles. Print with 3 perimeters so that the top layer is as nice as possible. Print in the default position, no supports or skirt/raft is required. Can be printed of PLA too, but because of the heat from the PSU I recommend PETG.
