Or it's a ball bearing with a spool holder wrapped around it - take your pick! The PET-G version is suitable for spools with inner diameters less than 5cm (like the Prusa ones). The ABS version is designed for spools with an inner diameter ranging from 5cm to 5.8cm. These bearings are compatible with this Samla spool holder: https://www.thingiverse.com/thing:2399361 Feel free to share your results! Print Settings Printer Brand: Prusa Printer: Prusa Mk2 Rafts: No Supports: No Resolution: 0.2 Infill: 20% Notes: It's crucial to set the Z-Lift in your slicer to 2mm. To avoid crushing the nozzle against the steel balls, place the 4.5mm steel spheres when Z reaches 8.60. Use the "change filament" function (Prusai3 MK2) to pause the print while inserting the spheres. Tips: Utilize the new Slic3r "layer editing" function to enhance the detail and smoothness of the balls housing layers!
