Box and enclosure generators
A box generator builds a printable box from the measurements you type in: a case that is exactly 83 mm wide, a project enclosure with holes in the right places, or a gift box with a lid that slides or hinges.

About box and enclosure generators
Change a number and the walls, lid, hinges and clearances update with it, so you never have to model a box by hand.
The tools fall into three groups. General box makers such as the 3D Box Generator and the Designer Bee Box Generator run in the browser with no account. Both offer dividers and several lid styles, and the 3D Box Generator can put raised or engraved text on the lid. MakerWorld customizers add popular designs, such as Kong 3D's slide-lid and snap-lock boxes and a collapsible crate with folding walls, all free with a MakerWorld login. For electronics, the Parametric PCB Enclosure Generator builds a base with standoffs and a lid around your board, and a panel generator from the same author cuts holes for switches, USB ports and fans.
Board gamers have their own options. Deck in a Box sizes card boxes and token trays in the browser, and BGSD designs full box inserts, though it is a desktop app and needs OpenSCAD installed to export the STL.
Before you print, check whether a tool asks for inside or outside sizes, and measure what goes in the box with calipers.
Boxes: what to buy
The generator does the design. These materials make the print look as good as the preview.
PETG for functional and outdoor prints
PETG handles heat, sunlight and repeated flexing better than PLA, so Gridfinity bins in a hot garage or signs mounted outdoors keep their shape.
- Bambu Lab PETG Basic (affiliate link) Upgraded formula that Bambu says matches PLA Basic for strength while staying impact-tough; low price per spool in multi-roll bundles.
- Polymaker PETG (affiliate link) High-flow replacement for PolyLite PETG: strong, low-odor and quick to print. In Europe? Buy from 3DJake (affiliate link)
Code gives 15% off your first order at Polymaker.
- Overture High Speed PETG (affiliate link) Good-value PETG in a large color range for functional parts in bulk.
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)
- SUNLU Matte PLA (affiliate link) Low-cost matte option for large batches of bins and baseplates. In Europe? Buy from 3DJake (affiliate link)
M3 screw assortment
M3 is the default fastener size for printed enclosures, hinges and mounts; a sorted kit of lengths saves a hardware-store trip whenever a model calls for bolts.
- Bambu Lab Fastener Kit Mixed self-tapping and machine screws with nuts, matched to Maker's Supply projects.
- Hilitchi M3 socket head cap screw assortment kit (affiliate link) Classic boxed M3 assortment with nuts and washers in many lengths.

Boxes: common questions
Do box generators use inside or outside dimensions?
It depends on the tool, so check before you print. The 3D Box Generator and Kong 3D's Slide Lid and Snap-Lock boxes take outside sizes, so thicker walls leave less room inside. To fit an object, add two wall thicknesses and some clearance to its size. Enclosure tools such as the PCB Enclosure Generator start from the board instead.
How do I make an enclosure for a circuit board?
Use the Parametric PCB Enclosure Generator on MakerWorld. You enter the board's length, width and thickness, the mounting hole positions and the height of the tallest part, and it builds a base with standoffs and a matching lid. Measure the board with calipers first. For a front panel with switch, USB or fan cutouts, use the Electronics Panel Generator.
Which box generators work without an account?
The 3D Box Generator, the Designer Bee Box Generator and Deck in a Box run in the browser with no sign-up and export STL. BGSD is free and needs no account either, but it is a desktop app and needs OpenSCAD installed to export. The MakerWorld box customizers are free but need a MakerWorld login.
