v1 model

This was created for using two small pieces of sponge, paper napkins, cotton, or any similar material you have on hand. You will only need these materials along with the three small printed parts.

Check the print external first checkbox in PrusaSlicer (Ultimater Cura, BambuStudio, etc).

No supports needed.

I hope you find it useful.

Happy printing!!!

Update v2 17/11/0023

This is just a refined model, adjusted for printing in the Bambu Lab X1CC, but you can print it in any printer you have.
The idea of this print consists in cleaning dust from that old dusty filament.

You wont't need any aditional parts, only cotton, a piece of paper towels, or anything you have.
