Torus tablet stand.
thingiverse
Donut or torus shaped tablet stand, well sort of because its deformed with a lattice matrix, so its easily customizable in blender to fit your needs. Edit: I printed it now (Pictures will follow in the weekend) and it works like a charm! It can hold my quite heavy Acer A510 in both portrait and landscape without feeling like its going to tip over.
