Gliding Adjustable Spool Holder for the Original Prusa i3 MK3 ENCLOSURE -Ikea Lack table

thingiverse

During my first print after completing the enclosure, I observed that the filament became extremely tight when the print head reached one side. The extruder motor struggled repeatedly with this issue. It was evident that the plastic bearings were not sufficient. Before starting to use the enclosure, I had been employing the Prusa i3 MK2(s) & MK3 Spool Holder - Frame Mount - Top Loader, which represented a significant improvement over the original spool holder that came with my printer. This new setup solved a similar problem where filament was no longer ripped off the spool and potentially caused extrusion problems; instead, it would now glide smoothly off the spool. Here, I combined the Original Prusa i3 MK3 Enclosure adjustable spool holder (https://www.thingiverse.com/thing:2864118) with the Prusa i3 MK2(s) & MK3 Spool Holder (https://www.thingiverse.com/thing:1832235), which has effectively resolved the problem. There is no longer any struggling, and the filament glides elegantly off the spool. I have included all necessary parts to build one spool holder, excluding the metal bearings. The assembly process is quite straightforward; however, if you need assistance with assembling the bearings, refer to Thing: 1832235. I printed the tire, spacer, and screw in PETG with 100% infill, as anything less resulted in cracking. The Adjustable Spool Holder can be printed at 25% infill. You will require four 608 bearings for each complete spool holder. I used these from Amazon: https://www.amazon.com/gp/product/B07PLV9YQ3
