An upgraded Geared Extruder v.2 (http://www.thingiverse.com/thing:933829) iteration features a spring-adjustable tensioner and customizable stepper position placement (optional for easier maintenance or if gears have an uneven surface). However, this version remains untested; thus, those seeking guaranteed reliability should opt for the previous model. This revised design requires: 6 x 10mm M3 allen head bolts, 2 x 30mm M3 allen head bolts, 4 x M3 hex nuts, 1 x 50mm M5 hex head bolt (for axis), M5 washers, M4 bolt and nuts for spring tension adjustment, a ~25mm spring, an MK8 gear to drive filament, 2 x 625ZZ bearings, and 1 x 608ZZ bearing.
