If you like my work, please consider buying me a coffee! Thanks! [https://buymeacoffee.com/klingy23](https://buymeacoffee.com/klingy23)

I needed something to clean my keyboard and the inside of my computer easily. I designed this simple, small TPU mini air duster to help me with it.

Please, make sure to calibrate and dry your TPU before printing, as it is a rather difficult filament to print with.

Also make sure to enable the “AVOID CROSSING WALL” option in the Quality setting in the slicer.
Slow printing speed is recommended.

The default .3mf profile was created thanks to @jimcorner 's High Speed TPU Printing Profile. It should give you a better end result when printing TPU at higher speeds.
