Avionics Bay Black Powder Well

Avionics Bay Black Powder Well/Canister.

A 4-40 screw will fit in the hole at the bottom of the charge well.

Can be printed with just about anything.  I've used PLA and PETG.

Small can hold slightly more than 2 grams when using an e-match.

Big can hold more than 3.2 grams of black powder when using an e-match.
