About this 3D model

I tried to implement the "stem" in my designs as much as possible, in this case I desgined a 3D printer nozzle where the stem represents the filament being extruded, akin to the Printception collection. For ideal results the nozzle should be printed in a greyish metal color filament. Unfortunatly, as a student, I haven't been able to get the income for a 3D Printer, which is why I'm so invested in this competition and you will see a lot more of my submissions. The fact it had to be printed upside down messed a little bit with my designs but it shouldn't be too big of a deal. Ideally I would've printed the model to test it out, but it should be able to be printed fine with no or very minimal supports.
