The following vendors sell specialty items related to the ShapeOko, but have not joined the Forums or contributed to the community. Please research carefully before purchasing from them.
- http://shop.myhobby-cnc.de (Ronald Holze) --- offers ShapeOko 1 and 2 Kits to Austria, Germany, Switzerland, Netherlands, Denmark and Italy
- minifab.net --- these people couldn't even be bothered to build a machine to photograph, instead stealing Inventables' photographs and doing an obvious job of airbrushing their logo on.
- Shapeoko 2 kits are available from Robosavvy.
The product originally used two companies for parts, and during the Kickstarter campaign a 3rd company supplied parts.
Materials availability is a tradeoff between price and convenience.
Further considerations include local business practices and shipping costs.
Please list only inobvious / specialty sources. There should be no need to list specialized sources such as lumber yards which are easily found by a search engine (and even have their own specialized search engines: woodfinder.com (U.S.), UK Workshop). Usually sign and glass shops are willing to special-order sheets of material(s).
