I printed this for my Black and Decker Dustbuster handheld vacuum so that I can vacuum small crevices and into tight areas.
I printed mine with TPU, it should work fine in PLA or other hard filament, but I feel like it would work best printed in a flexible material.
This is a “press fit” and I feel like it works rather well. There are other similar designs on here, but I wasn't a fan of the designs & the one I did print didn't fit.
The author marked this model as their own original creation.
