I have an Ivar felt shelf situated right behind my workbench area and wanted to be able to reference things on my tablet without it taking up valuable surface space - so this simple bracket allows you to mount the tablet snugly on that shelf facing outwards.
Make sure you print two for a tablet as they're only 25mm wide. Print them on their side and 15% infill/2 walls should be plenty. The included profile should work great.
Freecad file also included for modification.
