Vacuum outlet diffuser

thingiverse

Vacuum outlet diffuser redirects air flow for a 2.25in vacuum outlet, minimizing debris kicked up by airflow. This diffuser has no impact on sound levels and is not designed as a sound reducer. The diffuser did not appear to reduce vacuum inlet pressure. A project to learn OpenSCAD techniques resulted in this diffuser, which is less elaborate than commercial models but functions well. The fit is loose in my vacuum but does not dislodge when the vacuum is on. Adding tape around it would provide a snug fit if necessary. A filter mesh could be added inside for extra filtration.

How I Designed This Diffuser: Using OpenSCAD, digital calipers measured the outlet hole in my vacuum. Within the software, I created holes using nested 'for' loops for placing cylinders on the body wall and base. Iterations occurred until the design was refined. Initially, too many holes in the base caused strong airflow; fewer, smaller holes were added to direct air to the sides. Air dissipated within about one foot from the diffuser.
