Large thread spool holder for Singer Heavy Duty

Since the standard spool holder in the Singer Heavy Duty is way too small for my threads, I designed a larger one.
It's 11 mm in diameter and 65 mm long.
It was tested with 4432 and 5523, it should probably fit Bernina as well.

Print with the thick end up, (flipped 180 degrees on Y), I used 0.15, on 0.20 I had fit issues.
It is with extremely tight tolerances, to be stable, I recommend printing a short version (cut) to test the fit, and scale if needed.
