Black Powder Ejection Charge Canister - Single and Dual e.Match

High Power Rocketry e.Charge case

This is a simple and quick to print recovery charge case in four sizes.  This uses standard electronic matches that when seated in the case, prevent black powder leakage.

They're designed for single use (pretty much like the e.match)

If for some reason after filling the case and snapping the cap on, you want to reopen the case, you can reopen the case if you grip the grove on the cap and giving it a twist. 

Set the layer height to .2mm with 100% infill 

NOTE:  ADDED STLs in dozen layouts

Basic assembly 

No load test for Gemini Joe capsule detachment

UPDATE: Dual e.match support canisters 

This allows for the same e.charge canister to be fired by a backup avionics system.   If you're running backup avionics but don't want the chance of double the black powder to fire, this is one solution. 

You need to remove the e.Match sheath when using this dual canister.
