Or it's a ball bearing with a spool holder around it, if you prefer. Pet-g version is suitable also for spools with the inner diameter of less than 5cm (like the Prusa ones) ABS version is for spools with an inner diameter from 5cm up to 5.8cm these bearings are suitable to be used with this samla spool holderhttps://www.thingiverse.com/thing:2399361 Feel free to share your result :o) Print Settings Printer Brand: Prusa Printer: Prusa Mk2 Rafts: No Supports: No Resolution: 0.2 Infill: 20% Notes: it's mandatory to set the Z-Lift in your slicer at 2mm. in order to avoid the noozle to crush against the steel balls, you must place the 4.5mm steel balls when z reach 8.60. To do it use the "change filament" function (Prusai3 MK2) to pause the print while you put the spheres in place. Tips: use the new Slic3r "layer editing" function to make the balls housing layers more detailed and then super smooth :)
