This is a model I designed for my Kitfox to drop a bunch of small army men paratroopers. Video here:
I printed in PETG and glued together the main pod. I tied a string to the latch and placed the handle inside the cockpit of my plane. Hardware required is 11ea of M4x16 bolts and 4ea M6x16 bolts.
The author marked this model as their own original creation.
