I put this off for years and it was about time to start taking care of the the props that I have collected. ( no more tossing them into my tool box. LOL )
Here is what I came up with and it came out OK (better then I ever imagined).
It is 13x12x3 and will hold 32 gas props and has a nice pouch for my prop charts, prop nuts,and prop balancer. Also has a strap to carry it if my hands are full.

Sweeeeet!
Very professional looking, well done!
One day I'll own enough props to warrent a box!
