About

This is a universal reusable spool for refills that screw together and center the refill core, using thin flexible tabs. They're used for centering but not to fully hold the spool so make sure you screw the two spool halves tightly to ensure it doesn't rotate. 

Check the Spring

It's a good idea to check the spring every now and then to ensure it's still flexible. Printed springs under compression for a longer period can lose its original properties (i.e. not flex back).  

If needed, do a reprint of the actual spring only.

About - Continued

Python Refill Spool is a special version of the Master Refill Spool but made specifically for the Python AMS spool holder so the spool screws directly to it.

It fits Bambu Lab AMS, Hydra, Hydra Pro and Python as well as normal spool holders and dry boxes where the spool runs on top of rollers but is generally not compatible with spool holders where you hang the spool on a rod as it has a threaded inner core matching the Python AMS. For best flexibility, use the Master Refill Spool. 

It is compatible with refill spools with an inner diameter between 78.0 and 96.0 mm so it should fit all common refill spools.

Print Settings

Print the parts in the direction I have set them. No supports are needed. I recommend using 2 walls and 15% gyroid infill.

You can paint the text and pattern in the slicer if you like (Use the Paint Bucket Tool):
