3D Key Chain
Get inspired with this Google Image Search for TinkerCad Key Chains! The key chain printed below took 13 minutes on Low on a MakerBot Replicator 2.
Limits and Consideration
Out of consideration to your peers and minimizing print time:
Your shape will be up to 5mm thick, up to 75mm long, and up to 25mm wide.
You may need to add at least one 2mm hole so you can attach a key ring.
A note about designing efficiently for the 3D printer: a design that is "laying down" tends to print faster than a design that is "standing up" -- laying down has fewer layers, and standing up has more.
