Colster Adapter (12 to 16 oz spacer)

Colster Shim. Makes your 12 oz can fit in the 16 oz Yeti Colster. It probably works on knock offs as well. It basically adds the needed height to your can.

There is a lot of good designs online but they all had a void space inside where water/condensation can accumulate and go bad. This design is uniformly 1.8 mm thick throughout. Water/moisture drains cleanly from it. When you print increase the shells/perimeters to make it 100% solid.

No supports needed if printer flat side down. Enjoy.
