Creality Ender 3 Spool Holder/Roller by 6mm BB

I could not get a BB of 4.5mm size, so I bought BB of 6mm size. But there was not much I could do with this.
So I made it.

It is a spool holder using 6mm BB. Of course 6mm BB acts as a bearing.

This is true when using 6mm bearings.
Do not fill the inside with BB. Leave 2 or 3 spaces.

It does not use bearings, but it is usable.
Or to lock the bearings so that they do not shake.
