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.

Using TinkerCad

Use the white cubes to resize objects.

Use the cone to raise and lower objects along the Z-axis.

Use the curved handles to rotate or flip objects.

Check Alignment, if applicable

Select All, go to Adjust > Align. Click on a gray dot to align to Top/Middle/Bottom, or Left/Center/Right.

Add a hole for key ring, if needed

For a hole, try Hole: Cylinder, and squish to about 2mm.

Select All and Group.
