Print made by me.
Most done with meshmixer supports and no raft on a MakerBot replicator 5th generation. Buying a 3d printer is like getting a RC model helicopter, you have to learn new skills and spend time, but in the end it is a rewarding experience.
Here is what came out of "vasemaker" on ipad. Printed directly from the app.
My 2 surviving extruders are at 0 z offset (nut just 4/3 turn over thread transition)
