Before you print — gather & dry
Gate: don't slice a case until every box here is ticked.

Print one, right the first time
Canary cases print flat in PETG, with no supports and the fits built into the model. Work top to bottom, and don't cross a gate until it's green. Your ticks are saved in this browser, so you can pick up mid-print.

PETG at a glance
The numbers that matter
Starting points for a 0.4 mm nozzle. Dial to your filament and printer — the exact reasoning is in the guides below.
Nozzle235–245°+5–10° over "safe" = stronger layers. Ceiling ~250°.
Bed80°70–85°. First layer a touch hotter.
Layers0.2 mmThe design datum for every part.
Walls45 for sealed builds. Walls beat infill.
Infill30%Gyroid — strong in every direction.
SupportsNoneEver. If it wants supports, it's oriented wrong.
Which material? PETG by default — indoors and under an eave. ASA for full sun
(hotter, enclosed, low fan). PC only where ASA isn't enough, on an enclosed printer,
with the fit coupon re-run. PLA for fit checks only — it creeps in a hot car. Gaskets and
the field-case boot are always TPU. Why, in detail →
Buying it: pick on-tolerance spools (±0.02 to ±0.03 mm) sealed with desiccant, and keep filament dry — brand matters less than QC. How to judge a supplier →

The build, gate by gate
Seven stages, no surprises
Each item has the why under it, so you know what you're guarding against — not just what to tick.

Calibrate on the fit coupon — print this first
Gate: fits good on the coupon → the whole catalog fits.

First layer — watch it go down
Gate: a good first layer is a good part. Abort and fix if it isn't.

Print the parts — orientation is everything
Gate: every part in its intended orientation, fan modest.

Check & assemble
Gate: parts cool, fits confirmed, screws snug — not cranked.

Weather / sealed builds — only if sealing
Gate: gasket, disc, vent in — mounted ports-down.

Honest ratings. A printed case is splash-resistant, not immersion-proof — only the field case even targets IP67, and every rating is earned by testing your unit, not assumed. See the field ratings guide in Resources.

Finish & durability — optional polish
Gate: looks and longevity, without wrecking your fits.
0/0
🎉 Every gate green. That's a Canary built the way it was designed to be — sturdy, sealed where it counts, and honest about what it can claim. Last touch: print the rule-checked case label for the outside.
Ready to slice
Print files — the Watch Station
The Watch Station's three parts as STL, rendered from the committed CAD
(canary_watch_station.scad), with a manifest of case version, source commit, render
date and each file's sha256. The case is in development and not print-validated: these are
the next files to print, redrawn from calipers on an earlier print. The Builder
renders the same source with your settings.
| Part | Prints | Size | File | sha256 |
|---|---|---|---|---|
| Display drum | open face up, no supports | — | — | — |
| Snap bezel | face down, no supports | — | — | — |
| Dock stand | base down, no supports | — | — | — |
Manifest: print-files.json. Print the drum and bezel first and check that the display lands on its seat pads and the bezel snaps home over the glass; the stand's dock clicks the puck in on two rails.

The honest ratings →On a Bambu (P1 · P2 · X1 · A1)
The Builder's 3MF opens in Bambu Studio in millimeters with part colors carried, and every Canary part fits even the A1 mini's 180 mm bed. Use the stock Generic PETG profile at 0.2 mm with the checklist's walls and infill; with an AMS, assign charcoal to the body and canary to the face for two-tone in one job. Print the fit coupon first, and feed the TPU gasket from the external spool holder unless your AMS supports flexible filament.
