Harbor Freight filter ring

This is to filter sand for the Harbor Freight sand blaster. This fits inside the funnel that is suplied with the sand blaster. You will need to print 2 of these rings and sandwich a bit of screen material between the 2 prints. I used 10 mm long screws/ bolts to clamp them together. If you've modified the sand blast pot with the 30 watt concrete vibrator motor, you will be able to filter a 5 gallon bucket in less than 5 minutes. If not, gravity will have to do the work.
