Anamorphic Corner Cube

You won't believe what you're seeing.

A solid (red) cube hovering in the corner of your room. It isn't there.

It's three flat panels.

Move your head — the cube tracks you.

Step too far — the whole thing collapses into painted plates.

Real anamorphic illusion. Real-world. All 3 panels fit on one print bed.

— Specs —

- 3 panels, ~1.5h print, fits 220×220 beds

- Mounts in any 90° wall + ceiling corner

- 2-tone paint: dark frame, bright interior (any colors work)

— Print Setup —

- Print flat, no supports

- PLA, 0.2mm layer (0.55mm with 0.8mm nozzle also works — faster)

- 15-20% infill is plenty

- Use the provided STL files (3 separate panels)

— Mount —

- Place in a 90° corner where two walls meet the ceiling

- Use foam tape, command strips, or small magnets

- Find the viewpoint: step back from the corner until the cube "snaps" into a perfect 3D shape

— Notes —

Files aren't perfect — they work.

No math. Pure eyeballing in Fusion. Stare too long and you'll go cross-eyed — that's the challenge. Remix it. I dare you. Drop your versions below.

Just HIT Print, (paint*), mount, find the viewpoint, watch jaws drop 

*(Or use a multicolor printer and skip the paint step entirely.)
