How do I price 3D print files?
Updated
A file is priced on design, not filament
A 3D model file has no material cost, so price it on the design work and on how much trouble it saves the printer. Models that print cleanly without supports, come with tested settings, and solve a real problem sell for far more than a quick sculpt. Compare against similar models for the same buyer.
Buyers of files are paying you not to waste a weekend on failed prints.
Printed objects are priced differently
If you sell the printed object rather than the file, your price has to cover material, machine time, electricity, failed prints, finishing and postage.
Work out the cost of one finished item first, then decide what your time is worth on top. Selling prints below that is a hobby, not a business.
Look at the shelf you are on
Find a handful of models aimed at the same printer and note where their prices sit. Start in the middle, not underneath.
A commercial licence, a multi-part set, or presliced files for common printers all justify sitting above the middle.
Free files still earn
Many designers release a simple model free and charge for the larger set, the commercial licence or the ongoing collection.
The free file is how printers find you. The paid one is where the design work is.
