Tangram Puzzle with Slider Box

🧩 The Puzzle

The Tangram puzzle is a classic dissection brain teaser originating from China.

It consists of 7 puzzle pieces and a slider box with a snap-in mechanism. In addition to the box shape, many other shapes can be built.

The puzzle offers a moderate level of difficulty, as while the pieces are simple, creating specific shapes can be challenging.

🛠 Print Settings

triangle_large and triangle_small must be printed twice.

The exact settings are not critical — your standard print profile should work fine. The external dimensions of the box are 110 × 110 × 10.5 mm.

I printed the puzzle with the following settings:

• Material: PLA

• Layer height: 0.2 mm

• Infill: 15%

• No supports

• No raft, no brim

The puzzle pieces are used on both sides.

⚙ Fitting Adjustments

• Lid Fit: If the printed lid jams or is too tight, reprint it with its width reduced by 0.1 mm or 0.2 mm in your slicer.

• Snap-In Mechanism: If the lid is too hard to close, file or sand it down slightly using a nail file or sandpaper until it clicks in smoothly. If the snap-in mechanism is not tight enough, you can print the lid 0.1mm or 0.2 mm wider.

• Pro Tip for Perfect Tiles: For a "factory-finish" look on both sides, print two half-thickness pieces (sink them 1.5 mm into the build plate in your slicer), mirror one set, and glue them together.
