The design is not my idea - I saw it in an instagram feed somewhere and created the model based on that memory. I have tried to find the similar model on model sharing sites as well as here on printables.com but no luck so far.
Unfortunately printables.com does not allow to mark the model as remix or reupload without defining original model so I ticked it as original.
The design is a pretty simple but awesome idea, I'd bow before the original creator.
As always I have uploaded the Fusion 360 file so you can alter the dimensions according to your needs.
Update #2023-12-29: I have found a similar one so I marked as the source of the remix: https://www.printables.com/model/675776-gear-phone-stand
Update #2025-01-03: uploaded a custom sized STL to fit with the 5.9 mm thick 11" iPad Pro.
The author remixed this model.
