Describe the object and its intended use before choosing a machine. Then keep enough design information for another person to understand, modify and reproduce the work within the limits of the material, process and permissions.

What this guide helps you do
A route-selection and documentation guide for a modest fabricated object. A digital file or open-hardware label does not establish safe manufacture, fitness for use, legal permission for every component or access to a particular machine.
Begin with the object and use
Describe the shape, approximate size, fit, surface and purpose you need. Ask what the object must do and what a failure would affect. Consider a hand-made mock-up or existing part before choosing digital fabrication. A visually convincing model and a component ready for repeated functional use may need quite different evidence.
Compare processes with a real provider
Ask a staffed workshop which process and material suit the proposed object, and what design changes may be needed. BLDG 61 lists fabrication tools and staff support. Its print-service page describes file review and an estimate. Confirm instruction, reservations, material, waste, finishing, timing and the total cost for the actual job rather than treating an equipment list as an entitlement.

Keep editable sources and production output
Retain the editable design, its units and version separately from any exported file used by a printer or cutter. Record the software and export choices needed to interpret it. OSHWA’s definition asks for documentation in a format suited to modification. A downloadable production file alone may not explain how the design was made or how to change it. Source: OSHWA Open Source Hardware Definition.
Check what documentation and terms cover
Look for drawings, a parts list, assembly information, relevant software and a clear statement of the released scope. Read the actual project’s terms before copying, changing or distributing it. OSHWA is a community definition; it does not grant rights to a particular design or certify a manufactured object. Preserve provenance and attribution information with the files.

Use the shared lab as a learning setting
Ask about the host’s rules for instruction, supervision, materials, cleaning and sharing knowledge. The Fab Charter describes a community resource with responsibilities for its users. Actual access varies by lab; its network principles and older equipment lists do not establish the machines, fees or support available at a local site. Source: Fab Foundation shared-lab and charter guidance.
Make a sample and preserve the result
Have a suitably supported sample made when it can answer a practical question about fit, finish or assembly. Label the sample and file version, record the provider’s process/material description and compare the result with the intended use. Keep the limitations visible. Pass on the editable source, production output and observations together instead of only the finished object.
A record you can use
| Record | What to write down |
|---|---|
| Object and purpose | Use, dimensions, fit, material questions and consequences of failure. |
| Provider and process | Actual route, instruction, access, material, estimate and timing. |
| Editable design | Source file, units, version, software and provenance. |
| Production package | Exported file, format, process notes and any required instructions. |
| Scope and terms | Project license, released portions, dependencies and attribution. |
| Sample and handover | Result, limitations, changes and files another person will need. |
Learning route
- Describe: Start with the object and use.
- Compare: Ask about process and access.
- Document: Keep sources, output and terms.
- Sample: Record what the result can show.
Checklist
- The process was chosen for an actual object.
- The provider has confirmed current access and cost.
- Editable and exported files are both retained.
- Units, versions and provenance are recorded.
- Open documentation is separate from product approval.
- The sample’s limits accompany the handover.
Resources and their limitations
OSHWA Open Source Hardware Definition
OSHWA Open Source Hardware Definition — Open Source Hardware Association
Use. Use the documentation and scope sections to look for editable source files and an explicit description of what is covered by the project’s terms.
Access and cost. Public reading; tools, materials, training, services and travel may cost extra.
Review and limits. A community definition for evaluating open hardware, not a license grant for any particular design, a product certification, a safety assessment or an endorsement of a build. Read the actual project’s license, dependencies and documentation separately.
Boulder library BLDG 61 fabrication access
Boulder library BLDG 61 fabrication access — Boulder Public Library District
Use. Contact staff about the actual object, file format, material, instruction, access and cost before booking or submitting a file.
Access and cost. Web information is free; printed objects have a stated per-weight charge and require an estimate. Verify the current total, access conditions and supplies directly; no paid job submitted.
Review and limits. Provider pages list tools and describe a print-request process, not a confirmed reservation or guaranteed result. The 3D-printing page includes older software suggestions and a typical turnaround; neither software currency nor turnaround was independently tested. The listed service does not certify the finished object for a particular use.

Fab Foundation shared-lab and charter guidance
Fab Foundation shared-lab and charter guidance — Fab Foundation
Use. Read the qualification guidance and Fab Charter, then ask the actual lab about its access, instruction, materials, responsibilities and documentation rules.
Access and cost. Public reading is free. Actual lab access, classes, materials and program fees require local confirmation.
Review and limits. Only the qualification and charter portions are used. The long page also contains older budgets, equipment and software lists that are not adopted as current prices or compatible tools. Network policy does not establish the availability, access or suitability of any specific lab.
Historical starting point
The Spring 1969 page pairs model-making equipment with Machinery’s Handbook, a detailed shop reference. Digital fabrication, editable files and open-hardware terms are explicit modern extensions. No historical dimensions, machining, welding, electrical or material procedure is adopted here. Locator: Whole Earth Catalog — Spring 1969, PDF page 55, printed page 53.
