XLR Straight "short" adapter

Straight adapter for 90 degree XLR (generic) connectors as seen in the following link
 

These connectors are somewhat modular and have the primary connector part inside a barrel. This barrel is keyed with a little nub and 2 flat sides on a lip of the barrel connector.

My design has 3 parts:
Barrel lock
Bell sleeve
Strain clamp

The barrel lock is slid over the connector cilinder.
The bell sleeve is first slid onto the cable PRIOR to soldering.
Once done soldering, you slide the bell sleeve onto the barrel lock making sure the bottom of the bell sleeve is flush with the barrel lock. Also Ensure that the barrel lock is propperly bottomed out on the thicker lip of the barrel connector. Once this is done you can slide in the strain clamp, and use 1 M3 screw to clamp it down.

Glue can be used on the outside of the barrel lock to permanently attach this. But the fit is so tight that it should hold without, but the strain releaf feature will be downrated. (its ample though).

Note that if it doesnt fit you take a knife, sanding paper or debur tool and remove a chamfer on the bottom of the barrel lock and bell sleeve. Due to printing the bottom tents to “elephant foot” out a bit. so this makes it fit better. Might still need 0.5% or 1% adjustments by size in your slicer for me it fit perfectly but your mileage might vary. 

No supports. 

Note: in the STL or STEP file you can embed an arrow, or add multi color fillament to help indicate the upside of the connector. I just use a paint marker because im lazy.
