3030 Spool Holder with 608zz Bearing Slots
Description
This basic spool holder uses 608zz bearings on press-fit 3D printed shafts to allow smooth movement of the filament spool. Designed to mount on the vertical extrusion using M5 bolts and T-nuts. Fit bottom screw and T-nut first, once secured top T-nut can be dropped in and will be held directly behind its hole by the bottom. Prints with no supports required but may need some minor finishing for fit of bearings and shafts. *Note: I've found this spool holder works extremely well with filament that isn't tightly-wound on its spool, such as TPU. If you have a spool that wants to unwind by itself do not use it on this type of spool holder because the bearings will allow it to unwind itself due to lack of friction.
