Note: Upgraded version: https://makerworld.com/en/models/503707#profileId-419202

After looking at some of the existing A1 Mini filament purge baskets, I decided to create my own version. This is the second revision, as I have since improved the design a bit. The new version very sturdily attaches to the X axis arm, and holds quite a bit of filament purges. I'd still recommend checking between prints, but generally I have gone quite a few prints before emptying it.

Very easy to install and remove via its little catch.

Should work on A1, but not certain since I do not have one to check clearances and that the mechanism is identical. If you print it for your A1 and it works, please let me know. Enjoy!
