This is a remix of a nice bomb drop mechanism located at https://www.thingiverse.com/thing:14190
The changes I made are...
Added a Bottom Plate that is permanently attached to the plane (I didn't trust Velcro for this). This design allows the Bomb Holder to be easily removed via two 3D printed nuts
Increased hole sizes to allow for M3 bolts as hinges
Added small recess to rear holder so a small spring can be hot-glued into place behind bomb. Don't make the spring too strong, just enough to cushion the back of the bomb, too strong and it may jam. It's not totally necessary, it'll just rattle a but...if in doubt, leave the spring off.
I'd recommend printing in PETG at .2 layer height with 40% Infill. I'd also suggest using a BBQ skewer for the bomb rail, slides super smooth and is light.
