or browse the library first →Anything that would have saved you time if someone had shared it first. A few ideas to get you thinking:
Flanges, hammer butts, damper components, player parts, cabinet hardware — especially obsolete parts no supplier carries.
Boring jigs, drilling fixtures, routing systems, alignment and regulation aids you built for your own bench.
Action geometry studies, historical reconstructions, patent drawings, measured drawings of rare mechanisms.
How you actually do the job — regulation, voicing, restringing, bridge work — filmed at your own bench.
CAM setups, tool libraries, print settings, material recommendations, and the lessons learned getting a part to fit.
Photos, failure points, before-and-afters — the context that makes a file usable, not just a mystery shape.
Don't worry about polish — worry about usefulness. The best entries include the reasoning, not just the geometry: what the part is, what it fits, how you made it, and anything that would trip up the next person. A clear photo and a sentence of context turn a file into a resource.

Piano technician after all, or becoming one? and the contributor application will open up.
This is how you'll appear on everything you share — every card credits its contributor and links to your profile page.
Your website and social links go in the fields below. Payment links unlock after you're approved.
These appear on your profile and on your paid items so people can pay you directly. Payments happen between you and the user — the library doesn't process or take a cut. See the Terms.
The library is for piano professionals. An approved member of the Piano Technology Library community will review your contributor request, and you'll receive an approval email or a request for more information shortly. The more complete your memberships, certifications, and experience above, the smoother the review.
CAD models, jigs, drawings, research, or a training video. Submissions are reviewed by the library before they appear publicly — you'll see the status below.
Payments go directly to you through your payment links — the library never processes money or takes a cut, and the file stays downloadable. Add your Venmo/Zelle/etc. in your profile above.
By submitting, you confirm this is your own work or that you have the right to share it, and that it doesn't include anyone else's proprietary designs. See our Terms & disclaimers.
Sharing a whole folder of models? Pick all the files at once — files with the same name (e.g. flange.step + flange.stl) are grouped into one item automatically. Set the shared details once; you can rename or edit anything after they're in review.
New contributors — piano professionals only. Check their credentials (PTG directory: ptg.org), then approve to open uploads for them.
Pending community submissions. Approving publishes them to the catalog immediately.
