Nozzle Size

[hkup1130]

Hi! Your project is super cool and I’m ordering the parts to make one. I was wondering what size nozzle you use. Do you drill out a nozzle to be 1.6 mm or is there a 1.6 mm nozzle that you purchase?

I have not built this project but a Petamentor v1 and I just drilled out the nozzle and sanded it(carefully), so there are no sharp edges.
