Electronics enclosures, ready to print

Put your board in a box — SnugBox makes the standoffs, fasteners and connector cutouts, and checks that it prints and closes.

How it works

From a board to a printer file in three steps

01

Pick a board or a template

Raspberry Pi, Arduino, ESP32, WAGO terminals, DIN rail, buttons and displays. No board in the library — describe yours in a couple of minutes.

02

Arrange the components

Drag them onto any face. The enclosure adjusts standoffs, clips and cutouts and shows right away where something gets in the way.

03

Download and print

3MF with the parts laid out, STL or STEP, print recommendations and a list of screws and inserts.

Features

Everything you would otherwise do in CAD by hand

Parametric geometry on OpenCascade — the same kernel as in professional CAD.

Connector cutouts

USB, HDMI, Ethernet, power — cut automatically where a connector meets a wall.

Five lid types

Screws with heat inserts, snap-fit, sliding, hinged or an open tray.

Printability checks

Thin walls, collisions, bridges and lid clearance — before you spend any filament.

Partitions

Split the cavity into compartments; dividers avoid components and keep the lid closing.

Your own components

Size, mounting and connectors in the editor, the look from a GLB or STEP file.

Export and links

STL, 3MF, STEP per part in print orientation and a link to share the project.
