About puzzle, game and board game insert generators
For inserts, Board Game Storage Designer (BGSD) puts a form on top of the Boardgame Insert Toolkit, so you set boxes, compartments and lids in fields instead of code. It is a free desktop app, and you need OpenSCAD installed to export the STL. Deck in a Box runs in the browser and sizes deck boxes and token trays to your cards.
For puzzles, JigsawMake exports a flat jigsaw in five outline shapes, Pixel Puzzle Maker in Bambu Lab's MakerLab turns a picture into a pixel-art mosaic, and PrintPal 3D Puzzle Maker cuts an existing 3D model into interlocking pieces. DiceGen and Dice Studio design custom dice with your choice of font and your own SVG symbols, and MachineBlocks makes LEGO-compatible bricks with a calibration tool for the stud fit.
JigsawMake, PrintPal and MachineBlocks all have a tolerance or calibration setting. Print one small test first, because the fit depends on your printer.
Puzzles & Games: what to buy
The generator does the design. These materials make the print look as good as the preview.
Multicolor PLA and color sets
Dual- and tri-color silks give a single-nozzle printer color shifts with no extra hardware, and a matched color set is what lets HueForge and color lithophanes blend thin layers into a full image.
- Bambu Lab PLA Silk Multi-Color (affiliate link) Co-extruded dual and tri colors that shift with the viewing angle; great for keychains and name tags.
- SUNLU Multi-Color Silk PLA (dual/tri/four-color) (affiliate link) Budget dual-, tri- and four-color silk for colorful prints without an AMS. In Europe? Buy from 3DJake (affiliate link)
- Bambu Lab PLA CMYK Lithophane Bundle (affiliate link) Four 1 kg spools (cyan, magenta, yellow, white) made for color lithophanes and handy for HueForge-style layering.
Matte PLA that hides layer lines
Matte filament hides layer lines and cuts glare, so raised lettering on signs and nameplates stays readable from any angle and a drawer full of bins looks uniform.
- Bambu Lab PLA Matte (affiliate link) Wide color range with AMS-ready RFID, ideal for multi-color signs.
- Polymaker Panchroma Matte PLA (formerly PolyTerra) (affiliate link) The former PolyTerra line under a new name: soft matte look and good value for printing Gridfinity in bulk. In Europe? Buy from 3DJake (affiliate link)
Code gives 15% off your first order at Polymaker.
- SUNLU Matte PLA (affiliate link) Low-cost matte option for large batches of bins and baseplates. In Europe? Buy from 3DJake (affiliate link)
6 x 2 mm magnets for Gridfinity
Gridfinity baseplates and bins are designed around 6 x 2 mm disc magnets pressed into the corners; they hold bins in place but still let you lift one out with one hand.
- Bambu Lab Round Magnet D6x2 mm (20 pcs) Exactly the Gridfinity size, sold in 20-packs, rated to 80 C.
- 6 x 2 mm N52 neodymium disc magnets (bulk pack) (affiliate link) Buy 100+ for full baseplates; check the listing really says 6 x 2 mm, as 3 mm-thick magnets will not sit flush.

Puzzles & Games: common questions
How do I make a board game insert without CAD?
Use Board Game Storage Designer (BGSD), a free desktop app for Windows, macOS and Linux that puts a form on top of the Boardgame Insert Toolkit. You set boxes, compartments and lids in fields instead of code, but you need OpenSCAD installed to export the STL. For card decks and token trays, Deck in a Box works in the browser.
Can I make a jigsaw puzzle from my own photo?
Yes. Obloid Photo Puzzle builds an interlocking jigsaw with the photo printed into the pieces in up to four filament colors, as an AMS-ready 3MF. Pixel Puzzle Maker turns an image into pixel art on a color-coded base plate, one print plate per color, so no AMS is needed. JigsawMake exports only the puzzle shape, so you add the photo afterwards.
Can I 3D print LEGO-compatible bricks?
Yes. MachineBlocks is a web editor for LEGO-compatible bricks, Technic-style bricks, boxes, corner bricks and brackets, with 3MF or STL export. Its calibration tool tunes the fit of the studs to your own printer. MachineBlocks is not affiliated with the LEGO Group, and its library uses CC BY-NC-SA 4.0, a non-commercial license.
