Hacklab was getting dusty and the roombas couldn’t get in the corners. So I designed a printable hand-held vacuum cleaner. It works, for some definition of works.
What you need
- A 3D Printer
- A DC motor
- Filter (some cloth; see later)
- Power Supply
Step 2: Attach motor to impeller chamber. (You may need to redesign impeller_chamer.scad and impeller.scad for your motor.)
Step 4: Insert filter and filter grip into bin. My best results have been with filters made out of commodity sink towels/cheese cloth (double layered). Originally I was using a bounce sheet (the things that go in your drier with clothing) but a piece of solder shot through that and came out the exhaust which wasn’t terribly safe.
Step 5: Tape bin to impeller chamber. Be aware that air escaping is an issue.
Step 6: Attach nozzle to bin.
Step 7: Hook up to a power supply, test, and enjoy! I upload a youtube video of some pepper getting sucked up here (thanks to Norman for filming!).
