A framework for digital spare parts.

Common Parts defines how spare parts are structured, published, and distributed digitally.

What is Common Parts?

Repairing an object requires the right part. Digital manufacturing makes local, on-demand production of spare parts possible — but no shared standard exists for how those parts are described, published, or distributed.

Common Parts specifies that standard. It defines how spare parts are structured in a registry and how they are attributed to their authors.

Common Parts Access is the first platform built on this framework. It is an open registry where spare parts can be published, discovered, and accessed.

Registry

Common Parts Access

An open platform for publishing and accessing digital spare parts. Parts are structured with standardized metadata and attributed to their original authors.

How it works.

01 — Search

Your appliance

By brand, product name or model number, as printed on the appliance's rating plate.

02 — Check

The reports

For each part, print reports tell you whether it fits your appliance.

03 — Print

The part

Get the file and print it, at home or at a fablab.

Thirty seconds is enough.

The index is only as good as its reports. There are three ways to take part, from the simplest to the most involved.

Report a print
Printed a part for your appliance? Say whether it works, works with adjustments, or not. A comment is optional.
One click
Suggest a compatible part
Know a publication that fits an appliance? Share its address and the appliance's model number.
One link
Publish an original design
Modelled a part? Publish it directly on the index, with its metadata and the licence of your choice.
One file

No result for your appliance? The search is recorded, and you can post a public request. Requests show designers which parts are missing.
