I am looking to get a new package design with a 2-piece cap system prototyped.
I want to model something similar to this axe spray in terms of functionality. The cap twists down to expose the sprayer. My school has a Z printer that uses plaster and charges $5in^2 and an SST that prints ABS plastic for $6in^2. Would this be functional with either of these materials? When I say functional I want the twisting mechanism in the cap to work and not the spray (just to clarify). What material would you use?
