Kossel Belt Tensioners

thingiverse

I'm excited about tensioner brackets that go around CR-10 printers and others, but I couldn't find one for Anycubic Kossel Linear Plus, so I designed this. It should work with any Kossel using injection-molded Kossel tensioners. Used with 1 x 20mm M5 hex nuts and bolts. You may also want to get normal t-nuts instead of the square Anycubic ones. It's recommended that you try to angle the main overhang directly at a fan duct. The filament version of the bracket has a small hole for PTFE tubing if you need to thread some through. Edit 6: [17 Sep 19] Decreased tolerance of extrusion hole from 21.2mm to 20.4mm. Edit 5: [27 April 19] Removed old files and fixed alignment of the bracket by using dimensions from bottom injection-molded corner brackets found in https://www.thingiverse.com/thing:2965780. (Those who printed my enclosure would notice). Edit 4: [14 April 19] Added a bracket with a removable cover, made curve more flush with extrusion. Edit 3: [25 Jan 19] Made pulley larger to reduce chance of breaking. Printed at 100% infill; it's recommended to print spares. Edit 2: [15-Oct-18] Moved hole for filament and made it big enough to squeeze PTFE tubing in. Also included a shorter knob. Edit 1: Made top screws for brackets more printable.
