It's been over 2 years since we added models. Most of these were created in 2023, 2024, or early 2025. My middle school son is learning his way through Tinkercad and Onshape.
He created nested rings that are fun to fidget. At 100% size, the rings stay together well and have enough clearance for the printer. We haven't tried different scales to test the limits.
Two different versions are included.
Hope they print well & you all enjoy them.
The author marked this model as their own original creation.
