I have noticed that A1/A1mini have issue when poop shoot out of my bin when starting a print. So I made this design, there are many similar design already out there, so this is another one.

Easy to print and cost very little filament (around 6g).

Material:

Suggest to print with ABS, sometimes the filament poop is hot and will stick on the purge guard and cause issues. ABS or other high temperature reistant material is preferred.

Print suggestions:

If you are download the raw file, make sure you to the model in correct orientation.
