Full-Sized XLR Port for NATO Rails

I designed this to allow for phantom power to be used on the Blackmagic pocket series, as other Mini-XLR adapter cables which are able to provide phantom power are often clunky and expensive. It should also work well on any other camera with a Mini-XLR port, such as the PYXIS & Canon C70. If it has a NATO rail and Mini-XLR, it will work!

You will also need:

2x M3x30 Bolts

6x M3x10 Bolts

2x MnS Square Nuts

1x Neutrik NC3FD Panel-mount connector

1x Mini-XLR Male cable - this can be any mini-xlr connector, I would however recommend a short cable length 

Printing

• Print the backplate top-side down and main body/outer camp front-side down for a nicer surface

• 3 Perimeters for better strength in the clamp 

To Assemble:

1. Insert the two square nuts into the slots of the clamp - these slots are a bit tight to make sure the nuts to not fall out

2. Solder the connectors together with the correct matching pins (pin 1->1, 2->2, 3->3) colors do not matter.

3. Pass the cable trough the hole of the main body with the panel connector on the front and cable coming out of the back

4. Screw in two of the M3x10 bolts to attach the panel connector 

5. On the back, wrap extra cable length around the back pins of the panel connector to make a safety loop, and route the cable out of the slot behind the NATO clamp - you can also add a touch of hot glue to keep the joints from getting tugged on

6. Use the last 4 M3x10 bolts to attach the backplate 

7. Pass the two M3x30 bolts through the outer clamp and tighten into the embedded bolts - leave these a bit loose to be able to slide onto the rail

8. Slide your port onto the NATO rail and tighten the M3x30 bolts to secure.

9. Enjoy simpler in-camera audio!
