@Mike_Kelly_Mike_Make ​ I would say that a run of 10,000 parts would qualify as mass production. Though most of our production runs are much lower quantities. I have even printed special trays to hold and organize parts through different processes. It just takes a little planning and lots of pride in what you do!

The machine likely auto ejects the parts and that goes into a bin. Since these parts are not super high precision it doesn’t matter. It’s all about the bottom end, and 50 bucks for what they offer is almost nothing.
