That Nozzle holder apparently allows me to screw in the nozzles, i used sharpie for the numbers (hard to see), but it fit perfectly on top of the flux.
Only 9 spots for nozzles! LOL
How many nozzles do you need? lol
Now that I can print good prints with Flux, 1 working nozzle is plenty. I hate changing nozzles, you never know what may go bad! I have a printer that never worked well after nozzle change, mind you it is a dual head (nightmare!) printer...
