Free 3d scans

I am sharing low resolution copies of my 3d scans so that the aftermarket community can use them to develop new parts. I will continue to update this library as I make more scans. The files are in obj format with two different triangle counts. Download them for free on gumroad here:

Accuracy of these scans is generally limited by how accurately the model is scaled (photogrammetry doesn’t know anything about scale on its own). I include a machinists ruler in my scans so that I can generate scale information. My testing shows the scans are accurate to less than .1%. Larger parts maybe be more accurate since I use a measurement span that is similar to the overall part size. This image shows some of the early scale testing on small parts and I have improved my scanning since I did this testing:
