This is a stand for holding a cell phone or tablet in many positions. It is particularly nice for drawing on a tablet that uses a stylus as It gets the tablet up off the table and allows easy rotation. The stand is meant to be used in many positions, upside down, with and without the leg, whatever will get the angle you're looking for. The leg also nests inside itself for travel.
This was printed at .2 with 50% infill to get plenty of strength. The sliding extrusion elements have .5mm tolerance between them. Since these parts need to slide through each other it is important to have no “squish" on the early layers, that will keep these from slide through each other. The rubber bumpers i have printed in ninjaflex but could just as well be a hard filament or completely omitted.
