Kossel mini spool bearing for BQ,ESUN,3DPlastX, CoLiDo etc

When I bought a CoLiDo reel I discovered that my previous bearing/spool holder was too small and the reel was hitting the bottom structure of the spool holder from ChrisParish.

So I designed an improved spool holder, with a taller, wider base, almost "universal" for my reels.

It's 51mm in diameter so it can fit the smallest reel from ESUN that I have. Without any other support it's ok for ESUN,BQ and CoLiDo reel (tested).

With an optional support you can use it even for 3DPlastX reel.
