Description
You are purchasing STL files for 3D printing. No printed item, materials, or accessories will be shipped. A 3D printer and any additional materials listed below are required.
Print nesting boxes that can be rearranged in a seemingly impossible order. The download includes the designs described below; see the filament, nozzle, and prediction-feature notes before printing.
The effect
Three nesting boxes are rearranged in an apparently impossible order. The prediction feature uses the transparent lid of the yellow box to show a selected playing card, as demonstrated in the video.
Printing guidance
- The original build used standard settings with a 0.5 mm nozzle. The listing reports a print-time reduction of around 30% with that nozzle; your results will depend on your printer and settings.
- Each box typically takes a few hours to print.
- eSun PLA+ is recommended; PET filament is also described as suitable for the thin walls.
- Print the large box in black to support the size illusion. Other box colors are optional.
- Walls are 1 mm thick. Scaling down can weaken them and cause crumbling.
Customization
If you need a lid separated from its box, contact us to request that variation.
