Robo3D R1 Bed Belt Tensioner

thingiverse

Robo3D R1 bed belt tensioners consistently malfunction. To enhance their durability, I revamped the design and recommend printing a few extra units to have on hand. The new component should be positioned at the same spot or only a couple of notches tighter than the original injected piece due to its slightly longer length. Regarding infill density, more is better, but MTS testing indicates that 60% infill performs nearly as well as 100%. My initial print had an infill of just 20%, and it's working flawlessly. The relaxation modulus of this specific PLA won't pose any issues with this part. Print Settings Printer Brand: Robo 3D Printer Model: R1 ABS + PLA Rafts: No Supports: No Resolution: Medium Infill: 20 or higher Notes: Install the tensioner on the bed, making sure the cut-out for the nut faces downwards. However, installing the nut upwards ensures it stays in place during assembly. I designed this component to minimize the need for scaffolding; if used, it might result in a cleaner print.
