I designed and printed a tablet mount to hold a large tablet such as a regular iPad in landscape mode or a smaller tablet such as an iPad mini in either landscape or portrait mode. This design uses a ratchet-like mechanism that when locks when holding an item. Like my easel design, this tablet mount collapses into a thin rectangle, allowing for easy storage as a solid, rectangular shape, similar to that of a standard cookbook. Additionally, by installing eight small magnets, the back does not accidentally open while being carried or transported.
I modeled this design by constructing a skeleton assembly with various sketches and planes to ensure that the geometry locks and collapses as desired. I made liberal use of Creo’s global interference tool to ensure that in any state, there would be no unintentional interference.
Pictured below are different orientations of the tablet holder. You can see in the interior view the eight small magnets that ensure the design stays collapsed and closed when being carried or stored. You can also see the way that the design cleanly collapses into a rectangle.
