Part: stand — one print, three pieces that come off the bed already hinged together: * the base (90 x 60 x 4) with four rubber-foot recesses underneath and two ears in front that carry an 8 mm lip for the phone's bottom edge; * the rest (60 x 50 x 4), hinged along the base's front edge, that the phone leans on; * the prop (60 x 71 x 4), hinged along the base's rear edge, with three notches across its face. Lift the rest, swing the prop forward over it and drop the rest's top edge into a notch: the two plates brace each other as an A-frame, and the notch picks the angle (about 55, 65 or 75 degrees from the desk). Fold both flat to carry it. Both hinges are mechanisms.pip_hinge (7 mm knuckles on a 3 mm pin, 0.35 mm clearance, teardrop bores) and the rack is primitives.notch_rack.

Printed flat, everything on the bed: the rest lies between the ears, the prop beyond the base. Nothing flexes, so PLA is fine; PETG is also fine. Free both hinges with a firm twist as soon as the print is off the bed. The part reports as three bodies: that is the two hinges.

Assumptions (user unavailable): phones 65 to 85 mm wide (the bottom corners sit on the ears' lips); no cable slot; hinge length 60 leaves 14.5 mm ears either side.
