20x20 Frame Mounted Spool Holder on Bearings

thingiverse

Nice spool holder that mounts on 20x20 mm extrusions, I mounted it on my Creality Ender 5. The holder fits spools Ø110 mm and up; as far as width goes it can be adjusted to fit up to ~77 mm wide spools. I printed it in ABS but PLA and PET-G would also work fine since it does not have to have any particular properties. You will need: * 8x 5x11x4 mm bearings * 4x M5 nuts * 4x M5x20 mm Allen bolts To mount it to the frame you can reuse the same bolts and T-nuts used in the original Creality spool holder (2x M5 T-nuts, 2x M5x10 Allen bolts) This part greatly increased the quality of my prints: before using it the spool was shaking the whole printer frame when retraction occurred, now the filament feed is way smoother. I suggest orientating the parts as shown in the picture. You will have to activate supports: if well-tuned they will come off pretty easily, in case you encounter any difficulties just place the parts in the freezer for a couple of minutes (the supports will get brittle). FYI placed quite a few reinforcement ribs in order to postpone as much as possible any creep deformations if printing in PLA Link to the bearings: ITA: https://www.amazon.it/MR115-2RSMini-Cuscinetti-Cuscinetto-schermatura-cuscinetti/dp/B07CXN1143/ref=as_li_ss_tl?&linkCode=sl1&tag=fuskiapp-21&linkId=6d9240d1e94a5ce6ce3891af62ea1a6c&language=it_IT US: https://www.amazon.com/dp/B08531G3GT/ref=cm_sw_r_cp_awdb_imm_t1_qR58FbSH4GQMM
