3D Printed Vacuum for 3D Printer Cleaning

This started after using a cheap and poorly built $2 USB powered vacuum to clean my Bambu Lab P1P.

The design is based on reviewing several other 3D printed vacuums made by people over the years and some testing.  I've divided it up into sections for printing so others can made alterations or add-ons easily for this.

I used a piece of a used dryer sheet and a rubber band on the chamber plate as a filter screen but you can use any type of cloth as long as its not too fine of a mesh.

The motor and USB cable came from a cheap USB-powered Vacuum from AliExpress and the switch was also from there.  I'm sure you can find any hobby motor to do the trick.  Uses M3x4 and M3x8 course screws for assembly.

All sections were designed in OnShape, you can modify and make add-ons by clicking here.  (Requires Account)
