X axis tensioner for Prusa i3 Xl

thingiverse

I recently upgraded to an extremely large printer with a print bed measuring 40cm in size, and I quickly realized that my previous tensioner simply couldn't handle the extra force required. This led me to design and build a sturdier new Tensioner specifically for the X-axis. Built to support 608 Bearings, this device is designed to accommodate rods with diameters of either 5/16 or 8mm, all secured firmly by means of a sturdy 3 x 20 screw operating through a reliable 3mm nut. Tensing Requirements When printing your tensioner, make sure to use the settings outlined below: layer thickness at 0.2 mm and a speed of 50 with an infill percentage set to 40% worked well for me, but you should feel free to experiment until achieving satisfactory results.
