I have three HP inkjet printers and a large, old flatbed scanner. Both are a great source of steppers and linear motion components (slides, rails, bearings, etc). Many folks have made their own small CNC mills (think: Dremel motor, 8x10 XY table, etc) for milling circuit boards and other small pieces with parts just like these.
Here's the deal: To keep clutter down in the Factory, you pay me $30 and take out whatever pieces you want. You give me the rest back (plastic cases, glass, unused electronics, etc), which I will recycle, and then I give you $10 back. Deal?
