Many of you will no doubt be familiar with the McMaster-Carr catalog of parts and supplies. They carry over 550,000 items ranging from screws and bolts up through pretty much any industrial part you can think of including lasers.
McMaster-Carr is already responding to this incoming threat to their business model [4]. Currently, McMaster-Carr offers STL files for certain parts for free to be downloaded from their website. In addition, the CAD models McMaster-Carr provides with each order can be converted into an STL file. The idea is to allow the user to test out a part before ordering a durable and reliable version. McMaster-Carr is already training consumers that their website can be a location for high-quality STL files [6].
