Hardware Store (HS) Extruder
This is a variation on the extruder design (sans heater at the moment) that can be made from elements found at a common hardware store. Total cost for the extruder without the drive motor or any electronics is approximately $20. The great benefit of this extruder is that it can be made without exotic materials and with a minimum of tools; namely a drill press, a hack saw, and a couple drills.
The basic steps to construct this extruder are to fabricate the tension bearing bracket, fabricate the frame, strap the drive bearings to the frame, attach the drive screw, assemble the tension bearing bracket, and then attach the tension bearing bracket. Of course, calibration follows each of these steps and the build as a whole so this simplistic view of the construction maybe isn't correct enough.
