• ✓Flare runs into the head blockthe flare grows to 15.6 mm across, 1.5 mm inside the block's rounded edge, and enters the cup with 0.0 mm of straight neck showing
• ✓Ball captured past the equatorsocket wraps 37 deg past the equator; opening 19.6 mm vs ball 24 mm (21.6 mm across the flats, so even panned 90 deg there is 1.0 mm of lip); pulling either joint 1.15 mm out hits the lip
• ✓Joints print free0.35 mm surface gap all round each ball; 1.01 mm between ball and socket at the bed
• ✓Tilt cone at the clamp jointfree to 29 deg in all four directions (0.00/0.00/0.00/0.00 mm3); the neck meets the lip by 33/33/33/33 deg; pan unlimited
• ✓Tilt cone at the camera jointhead swings 29 deg each way on the arm (0.00/0.00/0.00/0.00 mm3)
• ✓Aiming pose cleararm leans 45 deg out over the desk (stud 25 + joint 20), camera level and facing forward; each joint at 20 of 30 deg
• ✓Ball neck takes a bump14.9 MPa in the 8.6 mm neck with the arm at its widest reach (55 deg from vertical), camera bumped (x2, root Kt 1.67); PLA allows 16.7 along the layers
• ✓Pinch screw holds the pose1.23 N m of friction from an M4 snugged to 0.4 N m vs 0.28 N m from the camera and arm at widest reach (x4.4); slit 1.2 mm closes 0.70 mm to grip
• ✓Clamp corners carry the bolt13.2 MPa inside the 7 mm corner bends (curved beam x1.70, measured sections 22 / 22 mm) at 313 N from a 0.5 N m knob twist; PLA allows 16.7 along the layers
• ✓Clamp will not rock on the desk5.3 N m of jaw grip vs 0.95 N m from the arm sticking straight out, bumped
• ✓Fits desks 15-45 mmM8 x 80: at 15 mm the knob sits 12 mm under the jaw, at 45 mm the pad clears the jaw by 3 mm; throat 54 mm
• ✓GoPro fingers fit the prongs3 prongs 3 mm thick with 3.1 mm gaps (15.2 mm stack), M5 bore, nut pocket in the outer prong
• ✓Thumb screw goes throughM5 thumb screw from the left into the captured nut
• ✓Prints in one goclamp, arm and head lie flat in a 219 mm square turned 21 deg on the 256 mm bed, 21.6 mm tall
• ✓Pad and knob sit on the boltpad pressed on the bolt tip against the desk underside, knob on the bolt head 22 mm under the jaw
• ✓camera arm stays together after printingall 3 bodies are captive: none can be pulled out along any axis
• ✓camera arm is held firmlyevery captive body is held by at least 0.8 mm (two perimeters)
• ✓GoPro goes in35 poses along its path clear of every part.
• ✓thumb screw goes in20 poses along its path clear of every part.
• ✓M8 nut goes in20 poses along its path clear of every part.
• ✓M4 x 16 pinch screw 1 goes in15 poses along its path clear of every part.
• ✓M4 x 16 pinch screw 2 goes in15 poses along its path clear of every part.
