This is my first attempt at making anything printable, and a way to teach myself about Inventor. It still needs some work, but I'm done wasting plastic on cups for a while. This collapsible cup is about the size of a shot glass, when extended. Its collapses down to less than 3/4" and expands to just over 1 1/2" tall. It prints as one piece. The outer layers have to be cleaned up on the bottom edge after printing. The handle is pretty weak, I think my next version will have a beefier handle. Printed on a Replicator.Print it solid, otherwise it will leak. No raft or Support needed! All the support necessary is built into the model. NOTE TO THING-O-MATIC USERS: You will probably need to scale this up to get a good print. The cup walls are too close together, and it wont print solid.
