Revised Spool Holder for Wanhao I3 Mini/Cocoon Model Create

thingiverse

I forgot to remove the 3D-printed spool holder with bearing while printing a 6-hour project and it failed on the fifth hour after the spool got dislodged due to lack of guard and proper locking mechanism. My carelessness led to this, so I tweaked the design to feature a guard that secures the spool in place and a notch on the other end fitting snugly into the hole in the spool holder to keep the part secure. If you don't have a 608zz bearing, I recommend printing this: https://www.thingiverse.com/thing:2746804, which is what I'm currently using as seen in the picture. I printed the axle at 95% scale, and for some reason, the same should be done with the original design to fit properly. I've printed three vases with this part on, and I must say that the tremors from the spool adjusting on the holder are now gone.
