thingiverse

This is an adapted design for the belt tensioner found on the Prusa i3 Hephestos, capable of working seamlessly across various Prusa configurations. A significant upgrade has been made to incorporate a reliable 606ZZ bearing, taking advantage of its robustness and dependability in demanding print operations. To secure this bearing, you will need to use a sturdy 6mm bolt, accompanied by two smaller washers, two larger washers, and a durable nut for ultimate hold. A strategically positioned M5 screw at the rear is specifically designed to provide continuous tension to your print system, accommodating any M5 screws of up to 20mm in length without any adjustments needed. When installing the axis fixer screws, they are precisely manufactured as M3 x 15 units and come equipped with their own robust screws that eliminate the necessity for any washers or spacers, all this is accomplished effortlessly. Furthermore, an impressive aspect of this setup is its assembly efficiency; it is straightforward and allows users to fix the belt tensioner in a hassle-free manner without needing to dismantle any components of the print axis. This new belt tensioning mechanism caters specifically to the demands of high-strength printing, perfectly optimized for prints that boast a robust solid infill configuration, especially with increased angles as much as five degrees beyond standard settings. To optimize the print results and take advantage of these settings it is recommended that brim options be activated and engaged during the printing process.
