I just looked at those. Those models are not particularly accurate.

Here is a photo of an actual Airlock Apollo electrical connector. On the left is the part mounted to the suit (Less the base disc) It's .907" tall and 1.067" in diameter.
I was going from memory in my earlier post, but you can now clearly see the circumferential groove , which is flat bottomed and centered on the fitting.

Weird. This is a photo from the Armstrong Suit. Seems different... still some differences to the model. I will make those adjustments tomorrow.

It's the same outer blue anodized piece. Has to be, they both connect to the same cobra head. What you see different in these shots is a central assembly that holds the electrical connector protruding out the top a bit.

Well as this part isn't accurate, figured I would test out the method of using wire to replicate the electrical contacts of the part. Using 1.00mm brass wire, straightened then press fit into the holes of the plug. Roughly trimmed to length with a side cutter then flipped the whole plug upside down and sanded with 100 grit to get all the contacts level. Finished up with some 180 and 220 grit to polish it up a bit and inserted into the connector.

Hopefully will do the same when I get my hands on some accurate connectors.

Look nice, but I think the pins should be rounded, not flat on the ends...

BTW, I revised my 3D file using Imgill's reference if you wanna try that...

I’m using PLA for most everything. When it comes to buckles and things that may have to support any weight I’m going to try ABS or a metal filament.

I'm thinking of using the Duplicolor VHT Anodized color coat paint. For use on non-metalic surfaces there is a base coat, and then the color coat over that. Here is the website: VHT Anodized Color Coat -- High Heat Coatings

The material I'll be painting it onto will be white Nylon, since that was the only material Shapeways offered as an option. This will be for the neck ring and gas connect fittings on the A7L, as well as the other anodized bits. I hope it's compatible with the material. I'll let y'all know.

I'm thinking of using the Duplicolor VHT Anodized color coat paint.
I used a very similar spraypaint for my couplings which I recently finished. It came out looking fantastic. I'll attach some pics of the spraycan brand and my couplings. I am still not overly happy with the gold on mine so might give them a repaint down the track.

My were 3D printed PLA material. After I smoothed them out I painted a gloss black RustOleum primer followed by a coat of Aluminium Rustoleum. Then I sprayed the Anodized in 3 coats according to instructions. The Anodized coat was a nightmare as it bubbled heaps and dripped as well for me. Not sure why it bubbled so much. I just waited for it to dry and sanded the area and recoated. Happy with the end results. Sorry for the subpar pics. They look heaps more 'metalic'' in real life.

Those look great! Nice job! I hope mine look as good. What paint did you use for the gold? I've picked up a couple different gold paints I'm going to try.

Thanks guys. For the gold I tried airbrushing Tamiya goldleaf but wasn't too happy with the colour. The one that I settled on is Dupli-Color Gold which comes in a spray can. Looking forwars to seeing how you go with your golds Red7.

Luckily the details were pretty easy to achieve. I just used bike ball bearings and red silicone o-rings for sealing gaskets which worked perfect and has a pretty good colour relative to the originals. I got the bolts from eBay too. I still need to touch up the white lettering alittle before I call it done.
