Shopvac Nozzle and Brushes for pipes

This is a custom shop vac nozzle designed to allow someone to clean dust and debris from overhead pipes and wires without climbing a ladder. The brushes are designed to be replaceable. After printing, cut out the center support ring with a sharp knife to free the bristles. To install the brushes, I would recommend wrapping a zip tie around the diameter of the brush to squeeze it enough to fit into the nozzle. Removing the brush to replace it will likely be a destructive process. You should be able to rotate the outer brush ring so you can cut it in half through the slot at the top.
This was developed as a piece of custom assistive technology for someone with balance issues to allow them to clean overhead without climbing a ladder, and keeps one hand free to brace on a cane or wall when cleaning.

The brush design is inspired by Turbo Sunshine https://www.thingiverse.com/thing:3355727.
