I do not sell any of my designs. I provide the 3D models for free to anybody that can print them. You can find most of my designs on Thingiverse under my profile page:
That said, you may not own a 3D printer and are wondering how you can purchase actual printed products.
Earlier in 2019, I wrote this article over on ToolGuyd.com:
The following is a list of vendors who have my express permission* to sell my designs.
*Note: You don’t need my express permission to sell these designs, but in that case you must abide by the Creative Commons Attribution-ShareAlike 4.0 International license. This means you must give credit to the creator (not infer that the design is your own), provide a copy of the license (or at least mention it so people can google it), and use the same license if you modify the design.
If you see somebody selling these parts that isn’t on this list and isn’t following the license correctly please let me know.
The Jake Of All
The Jake of All prints and sells several of my Milwaukee and Dewalt designs over on his store:
Jake ships both in the USA and internationally.
Another option to buy some of my designs is to purchase them from Swanky Storage. They have a vendor page on karpenter.co.uk:
Karpenter is based out of the UK, but I believe they ship internationally also.
brockoffroadparts also sells several of my designs on eBay and ships in the United states and several places internationally.
