Open Consumables

Measured baselines for everyday hardware.

Open Consumables is a measurement archive for everyday hardware. We don't manufacture, certify, or curate. We document the accidental open-hardware standards already running inside the consumer-goods aftermarket, freeze them as dated measured baselines, and publish so anyone can keep buying, printing, or batch-producing to fit.

What this site covers

• Project overview, what we do, what we don't do, and why
• The open consumables concept, the framing, the wedges, the prior art we look up to
• Categories, the consumable categories under measurement, starting with electric toothbrush heads

Current focus

The pilot category is electric toothbrush heads, working name OpenBrush. Five additional categories are scaffolded but deferred: air filters, water cartridges, robot vacuum consumables, electric razor heads, scooter parts, humidifier wicks.

See Toothbrushes for the active work.

Reference models

We look up to USB-C, VESA, MX-compatible, QMK as aspirational reference models. The realistic near-term mechanic is closer to ISO fasteners, generic pharma equivalents, and hospital procurement catalogs: substitutability of supply, not network effects.

Status

Pre-product. Public documentation reflects measurements as they land, not before. Specs are dated baselines, not stewarded standards.
