X-Belt Tensioner for JG AURORA A3

thingiverse

This is an X-belt tensioner I created to prevent rattling in the carriage. The thing printed with a 3D printer has low strength in the stacking direction. It was not designed to apply a strong force in this direction, so I decided to divide it into two elements and print them separately before gluing them together. I remixed this design from https://www.thingiverse.com/thing:1683070. To assemble this tensioner, you'll need the following parts: * M3x20 cap screw (1x) * M3 nut (1x) * M4x25 cap screw (2x) * M4 Nyloc nut (2x) * Timing Belt Idler Pulley: BIQU GT2 3mm:ID 13mm:OD Aluminum Toothless (1x) * GT2 timing belt (1.2m) Please note that this tensioner was specifically designed for the JG AURORA A3 printer, and I have not tested it with the Anet A8. The distance between the X axis rods on the JG AURORA A3 is 45 mm. According to a report from Mr. Kai_Nezeit, this design may also work with the Anet A8, but I haven't tried it myself.
