A wheel from the Mars rover Curiosity with a solid side, intended to sit like a cup. This could be used for a tea light, small flower pot, etc. The wheel design is remarkably accurate. Modifications made from original: I had to thicken the top rim in cad to avoid using support material. The step file is 50cm x 50cm x ~40cm, so it's been scaled down for this print to 8cm x 8cm x ~6.5cm. I had to turn on thin wall detection to get the wheel surface to print.

The supports are a little difficult to remove, and I welcome suggestions for improvement. The original wheel model was the only high-res version with the correct Morse code holes. The original model is from https://grabcad.com/library/test-mars-rueda-1. Thanks to NickGZ on grabcad for great work.
