Parallax Box + Pepper’s Ghost

Hologram Build Helper

Turn any phone or tablet into a parallax 3D display. Dimensions are normalized with a fixed +0.20 mm fit tolerance on width and height; depth only adds a thin bezel-lip light trap.

Fit tolerance: +0.20 mm (W/H) Depth allowance: bezel-lip only JSON download includes full BoM + cut list

3. Export & Fabricate

PDF export uses a pinned local jsPDF (3.0.2). It only falls back to the CDN if the local copy is blocked. Prefer the local copy for predictable behavior.
