Tough Drill Dust Catcher

I wanted to make a robust drill dust catcher that could be thrown into my tool bucket without getting too damaged to use. I also wanted to have fully enclosed sides and a flat upper and lower surface to easily hold it whilst in use. This is the third design I came up with which is the first that really met my requirements. 
The profile I've provide is in PLA. To be more robust you might want to switch it to PETG.
