Is it worth selling Cinema and camera small parts?

Q: Is it worth selling Cinema and camera small parts?

Worth testing, with a score of 57 out of 100. Film crews accept $50 for a small cap when a camera is rare and accessories are missing, but consumer camera owners compare against cheap machined SmallRig parts. It works for rare cine and rangefinder gear, and it fails on common cold shoes where metal wins.

Why it can work

Cine gear owners pay well for small parts
Discontinued lenses lack hoods
Dark matte prints suit camera gear

Why it might fail

Machined parts are cheap and stronger
Thread and mount tolerances are demanding
A dropped lens is costly if a mount fails

Be aware before you sell

Many printable accessories are community files, so check each licence. Camera brands are trademarks and lens mounts can be protected, so use 'fits' wording and do not copy an original hood's logo. Etsy asks for your own original design, so a licensed file may not qualify.

How to get a file you may sell

Make your own. Tinkercad is free and enough for simple shapes.
Buy a commercial licence. Many designers on Cults3D, MyMiniFactory and Etsy sell one. Read what it allows.
Use open licences. CC0 and CC BY allow selling prints. NC does not. Filter by licence on Printables or MakerWorld and keep a screenshot.
