Case Constructor
A web app that builds a 3D-printable enclosure for a PCB and exports STL:
pick a case shape, size it, choose where the lid goes and how it holds — the
app splits the shell, adds the lid skirt and lays both parts out for
printing.

Features
- Box with rounded corners and edge fillets, cylinder, console with a sloped
top, sized automatically around the boards.
- A catalog of 35 boards — Raspberry Pi, Banana Pi, Orange Pi, Radxa, Repka
Pi, Walnut Pi, Espressif ESP32, Arduino, Heltec — or your own board, on
standoffs with tap, heat-set insert or nut holes, or held by grooved rails;
against any wall with its connectors flush with the case's surface.
- Batteries — 18650, 21700, AA, AAA cells or a flat LiPo pack — in cradles
on the floor under printed clamp bars on screws, or ready-made holders
(MPD, with wire leads) screwed down like a board.
- Openings for every connector (captioned in the view: a click turns one on
or off), your own cutouts, ventilation, a fan seat.
- A lid on any face (the cylinder: top or bottom; the console: any face but
the slope), flat or taking part of the walls, with a skirt and a printing
clearance, on snaps, screws, magnets or printed screws (thumb screws in the
lid's STL, a matching thread in the posts); wall mounting (ears, through or
closed keyholes); a label on the lid.
- Exact preview: the same CSG pipeline as the export, in a web worker; the
boards drawn schematically inside, with their mounting holes, the case
exploded, assembled or laid out for printing, with a caption saying what
is shown; on a phone the settings slide over the view.
- Several boards arranged in a row, a column or compact, or aligned to each
other.
- STL export of the body, the lid (with its printed screws), or both in one
file, already oriented for printing.
- Built-in presets, your own presets in the browser, project files (JSON),
undo/redo.
- English, Russian, Ukrainian, Hebrew.
