This is a sturdy box to protect your drone propellers.  It is designed for the DJI Air 3s propellers, but it will hold any propeller up to 149mm.  The internal measurements are 21mm x 166mm x 149mm and it will hold 10 Air 3s propellers.  However, it can hold more propellers if they are removed from their plastic bags.  The seal on the lid is very snug, but it can be scaled for the tolerances for your printer.  Both the box and the lid can also be scaled up or down to fit your needs.  The box is a slim design so that it will fit in the front pocket of a backpack.

I recommend that the auxiliary fan be turned off so that there is no warping of the lid or box.
