Ender 3 - Ender 3 Pro - Ball Bearing Spool Holder
Have us print this for you
PLA from £6 inc. UK delivery on letter-sized prints. We slice, print on a calibrated Creality K2 / Bambu A1, QC and post.
Remixed to combine two parts and added some finishing touches like the cap nut that hides the hardware. Also added alternate hardware solution that uses more commonly available bolt style.
Works flawlessly - Works fine in PLA, just be careful not to over tighten the adjusting wing. Use the lock nut on the wing if you are worried about it coming loose.
I printed it in PETG for extra durability and it came out great. I did manage to break a PLA version but it was due to over tightening of the adjuster wing while mounting a spool.
Individual STLs for each part as well as a FULL KIT STL if you want to print it all at once.
There is also a modded main barrel with a 12mm center hole for adding a bushing if you like.
For PLA use 210 Nozzle Temp - 50 Bed Temp - 50mm Print Speed
For PETG use 240 Nozzle Temp - 80 Bed Temp - 40mm Print Speed
Use "Touching Buildplate" supports.
