Velleman K8200 Double Trapetzoid Z-axis

SummaryWith theese parts I have rebuilt my K8200 to double Z-axis. You will need the following 1 X original T5 belt (I have replaced my T5 with GT2 belt) joined with superglue. 3 X 608 bearings 22x8x7 2 X Trapetzeoid spindles TR8X1,5 or whatever 1 X Flexible coupling 5mm/8mm 2X M8 Nylock nuts Bolts, nuts etc. You need to adjuste the values for steps / mm according to your selection of trapetzeoid spindle. See video for it in action. https://www.youtube.com/watch?v=qmYXHTcvl8E Update: Credits to Stimpy for his original design! http://www.thingiverse.com/thing:259728
