How the work actually gets made

Play the fold, separate the assembly and inspect each component in the actual v0.3 CAD. Download the prototype files.

The locked outward hook and an unprinted inward candidate, at the same scale. Spin the actual meshes, compare the mounting mechanisms, follow the chunky facets and download the versioned models.

The two-boards-one-ring family, shot as a lookbook: TANG kitchen tongs (printed, benched, sanded, in use) and the converged KLEM clip — steel ball fulcrum and magnet latch sealed invisibly inside.

A tilting 0.96" OLED desk widget on an M3 friction hinge — the first-proof hinge+wire coupon, folding flat → open across three states + an animation, with the ESP32-S3-Zero and OLED it carries. Collision-free across the whole fold (swept-boolean gate); unproven until the bench.

A stand insert cut for the HS-02B, loose on my HS-02A. Tightening the two inner seats without moving a point of the exterior, proven to 0.000 mm. Measure → coupon → the bug → gauge → adversarial review.

The TP1 knob's reeded side, adversarially reviewed, then five printable alternatives — each as an AI beauty shot, a CAD render, and a live 3D model you can spin. Why FDM caps how fine a knurl can go.

The reusable loop: the fit-gauge, the three trust rules, the tool stack, and why a render is never a fit.
