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.

The emmet's bearing is made with 0.2mm tolerance.

In the middle you can fit an M3 nut. You could need an hammer to fit the nut inside. (or a wrench)

I printed mine in red CoLiDo PLA.
