Anycubic Linear Plus Belt Tensioners

I like the Y tensioner brackets going around for the CR-10 and other printers, but I couldn't find one for the Anycubic Kossel (Linear Plus), so I designed this. It should work with any Kossel that uses the injection moulded Kossel tensioners.

Used with 1 x 20mm M5 hex nuts and bolts. You may also want to get some normal t-nuts instead of the square Anycubic ones.

It's recommended that you try and angle the steep overhang directly at a fan duct.

Edit 8: [14 April 20] Corrected dimensions that were different from the injection moulded corners.

Edit 7: [14 April 20] Increased the thickness of Cover.stl, and made filleted versions of the knobs to get rid of all those sharp edges.

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 the alignment of the bracket by using the dimensions from the bottom injection moulded corner brackets found in https://www.thingiverse.com/thing:2965780.
(Those who have printed my enclosure would notice)

Edit 4: [14 April 19] Added a bracket with a removable cover, and made the curve more flush with the extrusion.

Edit 3: [25 Jan 19] Made the pulley larger to reduce the chance of breaking. Printed at 100% infill. It's recommended to print spares.

Edit 2: [15-Oct-18] Moved the hole for the filament and made it big enough to squeeze PTFE tubing in. Also included a shorter knob.

Edit 1: Made the top screws for the brackets more printable.
