Dabba

What is Dabba?

Dabba builds a hinged case around things you own. You measure each object, pick what it is (a box, round or capsule shape, a lying or stepped cylinder, one of 37 battery sizes, hex bits, memory cards or a custom shape) and the case gets a pocket for it with a fit clearance. The plan view lets you drag, resize and add compartments, and the 3D view shows the case closed, open at any angle, or laid out for printing.

You can make a base and lid joined by a filament-pin hinge, or a base only for a tray or drawer insert, and put either on a Gridfinity base with optional magnet holes. Further settings cover wall, floor and lid thickness, finger notches, an alignment lip, lid dividers, rounded or chamfered edges, clasps (snap hooks, magnets, snap bumps and latches), 27 outside textures, and text, borders and pictures on the lid top and base underside, each in its own color. Pick your printer to check that the parts fit its bed.

Export 3MF lays out the base upright with the lid open beside it, with colors written the way Bambu Studio writes them, so they come through in Bambu Studio, OrcaSlicer, Creality Print and PrusaSlicer. STL gives the same layout in one color. For the hinge you push a piece of 1.75 mm filament through the knuckles. It is free, has no account, and keeps designs in the browser, as a saved file or as a share link. The code is open source under GPL-3.0, which covers the software, not the prints, and the project says nothing about selling them. It is new (October 2026) and suits anyone who wants a fitted case for a tool, gadget or set of batteries.
