• ✓Hub, legs and ball head start on the bedall flat-backed at y = -5.5 (the print bed); legs, hub and ball flat print side by side
• ✓Every body prints freeworst overlap 0.000 mm³ with a 0.4 mm gap
• ✓Legs open to a hard stopfree at 30/30/30 deg; 3 deg further the cheek bosses bite the groove ends (1.4, 1.3, 1.4 mm³)
• ✓Legs fold flat and stop therethe same bosses stop each leg 3.1 deg past flat, so the pack stays flat in a pocket
• ✓Legs splay about 30 deg32.0 / 30.0 / 32.0 deg from vertical
• ✓Stop bosses take the load2.6 MPa shear per 3 mm boss (19 N each, 4.3 N per foot with a 10 N press); allowed 5.0 across layers
• ✓Legs are stiff enough1.0 MPa at the leg root (205 N mm); PLA allows 16.7 along the layers
• ✓Ball is captureda 2.5 mm push in any of 6 directions hits the socket (39.4 mm³ min); openings 14.7 mm front, 17.7 mm back for a 20 mm ball (1.2 mm lip)
• ✓Tilt conethe 8 mm stem leans 32 deg to either side before it meets the socket rim (5 deg more is blocked); pans all the way round
• ✓Nods 25 deg up and down with the clamp onhead and clamp clear of the hub and legs at +/-25 deg (0.00 / 0.00 mm³); the socket is open front and back for printing, so the lock knob, not a rim, sets the nod
• ✓Lock knob threads in cleanprinted screw vs its threaded bore: 0.000 mm³ at rest, 0.3 mm radial thread clearance
• ✓Lock knob holds the aima 0.15 N m finger twist pushes 63 N on the ball: ~0.31 N m of grip vs 0.09 N m from a 250 g phone (estimate, friction 0.25)
• ✓Widest, thickest phone fits85 x 16 mm: lifted 3.6 mm over the lower hook it still has 1.4 mm under the open top hook and 1.0 mm in front, and slides out clear
• ✓Narrowest, thinnest phone is held65 x 8 mm: the jaw reaches it; 3 mm hooks lap both edges (2 mm net of a 1 mm edge round), so tipping it 15 deg or pulling it forward hits them (50 mm³)
• ✓Thumb screw holds its griplead angle 14.2 deg vs friction angle 16 deg on 45 deg flanks: it cannot back off by itself
• ✓Top bridge takes the squeeze1.4 MPa in the bridge for a 40 N squeeze; 16.7 allowed
• ✓Clamp twists on and locksturned 45 deg it slides on and off the peg clear (14 poses, worst 0.00 mm³); level or turned to portrait the lugs sit behind the bore lip, so a pull hits them (15.3 / 15.3 mm³)
• ✓Stands steady in landscapecentre of mass 15 mm inside the feet, 143 mm up: tips only past 6 deg (230 g, 85 x 175 mm phone)
• ✓Stands steady in portraitcentre of mass 15 mm inside the feet, 136 mm up: tips only past 6 deg
• ✓tripod stays together after printingall 5 bodies are captive: none can be pulled out along any axis
• ✓tripod is held firmlyevery captive body is held by at least 0.8 mm (two perimeters)
• ✓clamp stays together after printingall 2 bodies are captive: none can be pulled out along any axis
• ✓clamp is held firmlyevery captive body is held by at least 0.8 mm (two perimeters)
• ✓phone goes in25 poses along its path clear of every part.
