FT-5 Z-Link bracket

This is a simple and effective z-belt linking mod originally created by nselimis and modified by me. Enjoy! Changes: Created a shorter version for 696 mm GT2 belts. Modified M3 holes to accept hex nuts whereas the original design requires screwing machine screws directly into the print. Tweaked the tensioner dimensions so the tension screw won't hit the idler pulley screw. Created an anti-slip pocket in the base for the tension screw. Required hardware: (1) (760 mm or 696 mm) closed loop GT2 Belt (2) 5mm bore double-headed GT2 belt pulleys (http://a.co/0pWd3dl) (3) 3mm bore GT2 belt idler pulleys (4) M3 hex nuts (1) M3x25 screw* (2) M3x20 screws** (1) M3x16 screw (2) #6x1/2 inch wood screws = This is simply the minimum recommended size. I'm using an M3x40 screw in my photos. *= M3x18 should work too. Assembly tips: Because I have vibration dampers on my z-axis motors, I found that I had to flip the gear pulleys attached to the leadscrews to get the belt aligned to the double-headed gear pulleys. Before tensioning the new belt, level the print bed by hand first. Then, using the LCD interface, move the z-axis down 1 mm. Doing so should lock your z-axis in place and prevent unleveling the bed while you tension the bracket.
