I made this to let me use the "Low Friction Adjustable Spool Holder for A1 mini" on my A1

[https://makerworld.com/en/models/565215-low-friction-adjustable-spool-holder-for-a1-mini#profileId-944742](https://makerworld.com/en/models/565215-low-friction-adjustable-spool-holder-for-a1-mini#profileId-944742)

Its an A1 mini spool holder using A1 threads so its fits on any custom printed A1 mount.

NOTES:  You will need to print an after market spool holder as the stock spool holder filament swivel has clearence issues with some spools.

I use this one and it works great. [https://makerworld.com/en/models/740921-a1-back-spool-holder-with-angled-filament-guide#profileId-673338](https://makerworld.com/en/models/740921-a1-back-spool-holder-with-angled-filament-guide#profileId-673338)

Switched to a ams pro top mount now I use this.  [https://makerworld.com/en/models/1834169-a1-external-spoolholder-remix#profileId-1958832](https://makerworld.com/en/models/1834169-a1-external-spoolholder-remix#profileId-1958832)
