Interesting approach, looks nice, neat solution without 3D printing or cases needed.

I have some more 3D prints to fit inserts into and have some headers on order to harvest the fork inserts from, just waiting for delivery of those. Once those are in I will have 2x each design available for soldering to a pcb.

I also have a third idea, I have some parts on order, once I get them I can start on another 3D model design and see if its practical.

So it has slowed a little, but once more parts are in I can get going again.

Version 2 using header fork type inserts, slightly less quality print but it still works. Bit fiddly putting the inserts in but by no means unachievable, might be a case of shipping the connector and inserts as a kit for the cart maker to put together.
I multi-meter tested the connections once fitted in the VB and got a signal, I also check each connection individually and got signals from all 60 inserts, so I think this will work, its a lot cheaper.
I'll get some more built and send off to get soldered to a pcb for a true VB test.
The legs are long, need bending around the cart inner but if we are to make the whole thing the cart model can be modified to accommodate this sort of leg length.
Quite happy with how this came out, 3D print worked out to around £5 each and the inserts were £2.50, can get these cheaper buying a stack of headers, I just bought the amount I needed, same for the 3D print, I can combine a few into one model and reduce costs.

Still hunting for small twin leaf (twin beam) inserts.

I have a second version on the go, 3D prints being finished and see them soon. It uses fork type contacts which worked out very cheap but I'm not wholly convinced on them connecting reliably as they are a flat fork rather than having sprung leaf's and 0.4mm is the low end of what they will contact to.
I'm going to make a prototype and see if it works and then how robust it is putting into & pulling out of the VB.

I am still searching for some small cheap twin leaf (twin beam) type contacts as those are what populate the originals.

Will post some pics once I have the fork insert prototype done, I am hoping I can 'test' it the same way as the pin insert one.

Yep the price for volume of the inserts (x60) drives the cost up.
I'm looking into using inserts from a long pin header, I can get some thru work to have a go with and if it does work out then the cost for the amount of inserts drops from around £8 to £0.50, so with a 3D print the connector should come in at a decent cost, if it works.
The tuning fork type inserts in the header are a basic flat stamped shape so should be able to find a cheap source for them if 'this is the way'
I have some parts due in the next week or so and will see what I can do to make them fit and work in a connector strip.
I'm not including any labour costs, but if it take too long to put them together then maybe offer as a kit of parts to be made as needed.

I have made a completely homebrew connector strip that fits the VB and works with a pcb game fixed, with help from Kev Mellott, he found the inserts and kindly provided me with a connector I could take apart and measure.

Pics enclosed of the strip, fitted into a VB joined to a game.

The body is a 3D print with 60x inserts pressed in, it fits in a cart case and fits in the VB and I just slotted another game connector and pcb into it to check it would fire up and it did, all works. Couldn't take a picture showing the game playing and the connector in place due to view angle thru the red lens, but it worked fine.

The problem is the metal inserts, these work out expensive for 60x per strip and means the strip I have made cost at least $20 for the parts alone. What is needed is to find a source for 'off the shelf' metal inserts that will accept a 0.4mm pin, be small enough to fit the connector pitch (2mm X 1.5mm) and have a solder tail end that can stick out the back of the connector, so need to be around 15mm total length. The type I have are round and I guess have been micro machined, could do with some sort of press formed type strip of inserts that only cost a few pennies each.

I have searched a lot, if anyone cares to take this up you may have more success, anything found please either pm me or post a site ref and pics here and I can check if I can make it fit a connector.

Thanks very much.


No problem.

I no longer have any left with logo on, all for sale are now plain.

Sorry bit late in getting to edit my model.

In reading this I saw the screw hole depth being too short and you can see the screw pushing material out in assembly photo, I have made this hole 0.5mm deeper, -rev1 STL model here in case its of use.

BTW these clear ones look good, red would be great.

reading stuff on the net came across a weird peripheral article, clicked and saw our beloved VB in it:

So how is the VB a peripheral I wonder?
