Bear Y idler tensioner (Patreon)

I am working on Bear Upgrade 2.1 and it will come with a better Y axis. This picture is a Y idler tensioner.

Some features:

• 3mm of adjustments like on X.
• Use a single tensioning screw to keep the mount straight and make adjustments easy.
• The movement use a small rotation but the height of the belt vary only by 0.042mm.
• Will be compatible with E3D idlers.
• Belt path is different than on Prusa but will be the same across all bear frames.
• Hardware needed: 3x M5x10 screws and t-nuts, a dowel pin (same as the X axis), 1x M3x25 screw, 1x M3x30 screw, 2x M3 nylock, 1x M3 washer.

As the belt path is slightly different it will need a new Y belt holder as well. I am planning to improve a little bit the Y motor mount to increase stiffness and reduce noise.

Hope you like it :-)
