Play Vacuum Cleaner
Summary
This design is fully customisable in OpenSCAD. The default dimensions work well and can suck up many small objects. I haven't optimised the impeller so feel free to experiment with different sizes and see if you can find a design that works even better.
Materials:
~11mm outer diameter plastic straw
Size 130 toy motor
2XAA Batteries
2xAA Battery Holder with switch
This is just a toy, use it for sucking up small bits of paper, rice, etc. There is no dust filter, so sucking up dust will just throw it into the air…
