3D printing

Make a personalized, printable object without CAD: a keychain, an event badge holder, a labeled Gridfinity bin or a phone stand. Every object is a parametric file built in manifold-3d. The CLI and /make/print run the same build, so the same parameters give the same file. Only make physical objects from this catalog; do not hand-write STL.

Workflow

makeables print list returns every object with its parameters (name, type, range, default, options) and asset slots. Never guess a parameter: read it from the list.
Build with a preview and look at it before reporting anything:

bash

makeables print keychain --param text=Hunter --param font=borel \  --out hunter.stl --preview hunter.png

makeables print keychain --param text=Hunter --param font=borel \  --out hunter.stl --preview hunter.png

Open the preview image (top, three-quarter and front views) and check that the text reads, nothing touches an edge and the logo is the right way round.
Read check and printability in the JSON result before handing the file over.

Parameters and assets

--param name=value, repeated. Numbers must fall in the listed range and whole-number parameters (cells, height units) take integers.
An asset slot such as logo takes a file path: --param logo=mark.svg. Logos must be <path> elements without group transforms. Convert shapes and apply transforms first.
--brand <slug|brand.json> takes the brand's logo and, unless text is set, its name. Curated slugs: sla, paisanos. A brand.json from makeables brand new and brand add-logo works the same way and uses its first SVG logo.
Fonts: plex-mono (default), borel (script) and silkscreen (pixel). A character the font lacks fails with a message that names it.

Two colours

--out file.3mf writes a two-colour print: the body, and a label made of the raised text or an inlay filling each engraving flush. Colours come from --colors "#body,#label", else the brand's paper and ink, else #f4f1eb,#141414. The file is one object with two volumes on extruders 1 and 2, the way PrusaSlicer saves projects. It was verified in PrusaSlicer. Other slicers should load it as one object, but tell the user to check filament assignment there.

What the result guarantees

check: { unpaired: 0, solids: 1 }: one closed, manifold solid. The CLI refuses to write anything else, so there is nothing for a slicer to repair.
printability.baseMm2: area on the bed. ceilingMm2: area of faces pointing straight down above the bed, printed over air (bridges or cantilevers). It is measured, not judged. The badge holder's lips are about 475 mm². fits: which of the Bambu Lab A1 mini, Prusa MK4S and Bambu Lab P1S beds hold it.
No real print has set thresholds for walls or overhangs yet. Do not promise that a part prints without supports beyond what ceilingMm2 says.

Objects

Object	What to know
`keychain`	Name in relief or engraved, optional engraved logo, 40 to 100 mm long.
`badge-holder`	Makeables 2:3 badge (60 × 90 mm) or CR80 card (54 × 86 mm). The badge drops in from the top behind 2 mm side and bottom lips. The event name goes on the band below.
`gridfinity-bin`	1 to 4 by 1 to 4 cells, 3 to 10 height units, with spec feet. The label shelf has a 45° underside and an engraved label. No stacking lip.
`phone-stand`	Lean of 50 to 80°, a slot for the phone with its case (6 to 16 mm), and the name on the front ledge. Prints upright with nothing over air.

For an event kit, use the event's brand so the object matches the cards, badges and stickers: makeables print badge-holder --brand <slug> --param text="<event>" --out holder.3mf.
