Pulley and idler for braided wire

thingiverse

Inspired by 3D printers that use braided-wire "Spectra lines" instead of timing belts, a game-changing innovation has emerged. The wire is tied to the pulley at its midpoint, eliminating friction as the primary force holding it in place. This clever design allows the use of virtually any non-stretchy wire for driving linear systems, offering unparalleled flexibility. Idler discs are designed specifically to snap onto 608 bearings with ease, ensuring a secure and seamless connection. Depending on the specific requirements of your 3D printer, you may need to scale up or down the idler discs slightly for optimal performance. The pulley itself is optimized for use with a 5mm motor axle featuring a flat profile. To accommodate different designs, the FreeCAD source code includes adjustable parameters that can be tailored to meet specific needs, providing ultimate customization and precision control.
