Tucked is an iPhone app (iOS 17+, by Little Inspiration Limited) that turns a photo of an object on A4 or Letter paper, or a set of dimensions, into a 3D-printable Gridfinity tray. Photos are processed on device. Pockets follow the object's outline, so it is not a full 3D scan. Adjust clearance and depth, then export STL for Bambu Studio, PrusaSlicer, OrcaSlicer or Cura.
The first 5 photo models are free, and dimension-based trays are always free. Extra photo credits are bought in app, never expire, and there is no subscription. Not affiliated with the creator of Gridfinity.
Little Inspiration Limited ships small native Apple apps that each solve one tactile problem, without accounts or cloud lock-in where possible. Tucked covers Gridfinity trays.
