Connector Witch Hunt

On that subject- here is a functional beta connector for the NA8 MAF male side:
1.8 miata MAF connector BETA by AlecMoody on Shapeways
What are people's thoughts on buying one off connectors? That $11.64 is cost from shapeways. If they were cost + $5 and you had to add your own pins would people order them?
Can anyone make a quick list of which connectors are the most in demand? I could add weather sealing to these connectors but it would be expensive since it is a lot of labor to make tiny little molds, degass and then pour a half oz of silicone.

If you want to break out the function of the maf or adapt it to something else, it makes more sense to use the male to adapt to something else unless I am misunderstanding the intent.
For example, you can take the female terminals and repin them in a housing they work with, like CONN-100453 here -> Home » Shop » Connectors / Harnesses » Sumitomo » 6 Way Denso diesel injection Pressure sensor Plug (+1 cavity plug). Then use the other side, CONN-100454 here -> Home » Shop » Connectors / Harnesses » Sumitomo » 6 Way Denso diesel injection Pressure sensor receptacle with terminals CONN-100069 & seals CONN-00145 and you can then adapt to whatever on the other side of that connection. You don't have to cut up your harness this way.
We already have both sides of the newer MAF on the NB iirc. CONN-75759 here -> http://www.bmotorsports.com/shop/pro...oducts_id/2077 , CONN-75758 here -> http://www.bmotorsports.com/shop/pro...oducts_id/2075 .
You can use CONN-100453 & CONN-100454 to match up the other side of the CAS using the same terminals but a variant housing with the same terminal count. Again, a solution that doesn't require a mold or complex work or cutting your harness, just an adapter.

The terminal that actually fits in the MAF plug is CONN-11856 here -> http://www.bmotorsports.com/shop/pro...oducts_id/1567 and the seal is CONN-00145 here -> http://www.bmotorsports.com/shop/pro...roducts_id/940 .

Also, unless the drawings are wrong the connectors you posted look like they are for the NB maf. I searched around for the NA maf connector earlier this year but gave up. If they are available I defiantly want to be able to order them.

I thought it was FDM but they do say SLS. It comes with powder on the parts and vertical inaccuracy typical of FDM and doesn't look like an SLS part. I think it might be a typo but it doesn't really matter. The Strong and Flexbile is far too inaccurate for the internal features I mentioned and the Detailed Plastic is borderline at best. Either process is ok for the external dimensions, & lock.
Shapeways is great for parts that don't require high accuracy or delicate internal features.

I agree that there needs to be simplified internal structure and that DIY connectors won't have the same fit and quality as the OEM versions. However, shapeways is being really conservative with their numbers. Their WSF is nylon 12 / PA2200 which doesn't melt until 340F. It doesn't appreciably soften until around 200F and it is a thermoplastic so it will stay stable through heat cycling.
Having a connector that is missing some internal springs is a lot better than sliding open pins into a connector and then wrapping it all in electrical tape.

As far as the housing, it doesn't make sense to me. It is a bunch of effort you don't need to spend, unless the effort is just a practice / fun endeavor.
Option 1 - Individual terminals in adhesive lined headshrink. Wrap some plastic from a student folder around it with tape, spray release agent and drop some RTV in for mechanical retention and sealing. Remove plastic and tape wrapping once hardened.
Option 2 - Get an alternate connector that accepts the same terminals, then use it's mate with a short wire length and the proper connector on the other end to adapt to your MAF of choice. This is far simpler and less time consuming. In this case, this is what I recommend and is easily achieved.
Option 3 - get about 2000 people together who want to pay a lot for this part and low volume injection mold it properly.
Either way, good luck!

Edit: Ooops, there was another page of comments. Nevermind. :-)

I'd love to see how they work in real life - breakable? Smooth enough? My (a few years back) experience was that 3D printed stuff wouldn't be up to that job - but if you've made one I'd love to see how it turns out....

CONFIRMED.
1. the GOOD. the VVT plug connector from an old Toyota Lexus fits the VVT connector on 2001-2005 VVT engines. They also come with a ~rubber shield~ to protect the plug connector from engine heat.
2. the BAD. most plug connectors of this type you'll find in the junkyard will brake the locking tab after you remove it from the sensor, must find another source but at least i gave you a lead.

thank you Leafy I am going to order the VVT and TPS pigtails as both in my car are missing the locking tab, for reference here is a link with all the miata connector components available on that website

To add to the spreadsheet:
you can find the alternator connector at advanced autosports (Replacement Alternator Plug [029-110-44001] - $13.95 : Advanced Autosports, Miata Race Parts, Spec Miata and TRANS AM Race Car Sales, Service, Build & Rentals Support in Midwest). It comes with a pigtail, but it's not hard to pull apart the connector.
