hi guys, I am "nooby noob" to the exciting 3D, and just wondered if you could help me. I am planning to buy Ultimaker3 for quite basic prototypes for Bottle stoppers (like on the photo), or plastic screw caps. My question is: What's an average cost of printing a single unit 3x3cm? Are there any extra maintenance costs I should consider using the printer for let's say 2-3 years? Also, which filament would be good to simulate that rubbery structure of a synthetic stopper? thanks, Parox.
