Tucked: Gridfinity Tray Maker

What is Tucked: Gridfinity Tray Maker?

Tucked is an iPhone app that makes a storage tray with a pocket shaped like your object. Lay the object on a sheet of A4 or US Letter paper, take a photo from above, and the app finds the outline on the device, using the paper for scale. You can refine the outline, then set the depth, clearance and finger notches and add more pockets to the same tray.

Gridfinity mode sizes the result to the 42 mm grid so it drops into an existing baseplate; otherwise you get a flat-bottomed tray. You can also skip the photo and build a tray from typed dimensions. The app exports an STL for your slicer. It is not a 3D scanner: it works from the outline, so it suits flat-ish things such as scissors, knives, pens and small tools.

The app is free. Trays from dimensions are free with no limit, and photo trays use credits: 5 come free, then packs cost $3.99 for 10 or $8.99 for 30, and they do not expire. It needs iOS 17 or later.
