Wanhao i3 or D6 Bearing Spool Holder - Quarter Holds It & 100mm roller

My bearing kept falling out of this particular spool holder and while it is a great spool holder, this was bugging me. This might be because the tolerances for my printer are different from the person who made this, but no matter!

I made it so that there is a small lip where a US quarter will fit to hold the bearing snugly in place without disturbing the rotation.

Also, if you've already printed the original one, you can do as I did and print just the quarter.stl part and superglue it on.
