Organisers and trays

3D printable desk organisers, valet trays, pen holders and soap dishes with compartments and drainage. Set the size and walls, then download the STL.

Trays and organisers built to a measured space. Six outlines, an adjustable wall height, and compartments laid out across the footprint rather than fixed at a manufacturer's idea of three.

For anything that gets wet — a soap dish, a sink-side tray — drainage holes and raised feet keep the base clear so water leaves instead of pooling under it.

Questions

What wall thickness should a tray have?

Around 1.6–2 mm — four passes of a 0.4 mm nozzle — is sturdy without being heavy. Go thicker only if the tray will carry real weight.
