eSUN Refill Spool (54mm inner diameter)

I increased the inner diameter to 54mm and changed the thread.

Thread tolerance = 0.35 mm so calibrate the flow rate beforehand.
Material used = ~150 grams

Edit: 

22.11.2024: 

• Now the whole model can be printed without support.
• added  thread testprints

• Part A: minor changes for a better look

I increased the inner diameter to 54mm and changed the thread which should be easier to print now.
