Solved: Where can you sell CAD files?
I would look for jewellery specific communities, rather than CAD-specific file sharing communities. If the community is focused on jewellery design then there will likely be a number of users who want to pay for great designs.
I’ve come across ‘Jewelry This‘ but I can’t speak to the quality of the community.
Are your designs in 3D or 2D? What software did you use to design them?
Hi Lolipop, have you seen https://www.ponoko.com/? I am not sure if that’s perfect for you but they 3D print and then let you resell your designs.
There’s also Jewellery 3d Market http://www.jewelry3dmarket.com and TurboSquid, https://www.turbosquid.com/3d-model/jewelry?synonym=jewellery
On the DXF files side these are being sold on Etsy, for example https://www.etsy.com/market/dxf_file and there are some DXF files sold on ebay too.
Finally there is DXF shop, http://www.dxfshop.com. I am not sure how popular these places are.
Are you looking to sell them to other Jewellery designers? There plenty of Jewellery CAD designers on LinkedIn so maybe you could also reach out to them too?
Hope some of those might help
