Pulley Locker 5mm - parametric

thingiverse

After several kilometers of filament, I often encounter issues moving with printed pulleys. This add-on prevents movement, extends pulley lifespan, and minimizes belt sawing risks during lengthy prints. The parametric design allows for customized inner hole sizes through a step value adjustment. The provided code, locker_series(outer_radius=7, radius=2.5, step=0.025, steps=4, distance=20), generates a fitting version. Markings on the top side indicate inner radius variations. A borehole is included for screw fixing, with a slightly tight fit for better grip. I'm currently seeking high-quality pulley replacements for my RepRapPro Mendel Tricolor. Consider MXL pulleys (16 teeth) and refer to the provided link for further details on the RepRapPro Tricolour x-axis assembly. Print these stoppers in PLA 0.4 due to heat sensitivity; high-speed printing may compromise quality, so print slowly or produce multiple stoppers.
