This 2x1x3 piece can hold 7 v6 3d printer nozzles. The labels are ideal for the E3d Nozzle Pro Pack and one extra standard 0.4 mm brass nozzle, which is included with most printers by default.

The model is heavily inspired by onelostcauses design: https://thangs.com/designer/onelostcause/3d-model/Gridfinity%20E3D%20V6%20Nozzle%20Fun%20Pack%20Holder.stl-62001
