Sandblaster

https://tinkersprojects.com/project/3d-printed-sandblaster/
This is a sandblasting gun for sandblasting and somehow this works and does not destroy itself within 3 mins. It works better than other blasters that I have used but will not last as long. It uses compressed air to suck in sand grit, accelerate it to high speed and shoots it out the end of the nozzle.
The nozzle helps the blaster to not destroy itself. the air inlet may need to be tapped to allow a better connection.

Note
I'm not sure how this part will do over time and with different printers and setting. Print and use at your own risk.
