Where to source GST18 connectors for large cable OD?

Q&A and troubleshooting

I’m working on hooking up my system, and plan on using some SJOOW cord (12 AWG conductors) to go from the MultiPlus to a Junction Box in the enclosure I’ve built from it. As you can imagine, the OD of that cable is a no-go for the stock G-ST18i that came with the kit. Even with the insulation peeled back, the stock connector opening is so small it squishes the 3 12AWG conductors / they can’t fit.

It looks like they make some with Cable OD ranges of 10.5.. 16.5 mm, but I cannot figure out who stocks them, even in EU (I’m in the US but if I need to order from EU, so be it). For example, this connector: Wieland Shop seems like it would work (I’ll need both male and female of course), but I cannot find it stocked anywhere. I don’t even care about the color, but none of the big OD ones seem like they are stocked.

Any ideas or other part numbers / brands that might work?

use the largest cable that will comfortably fit the connector, with about a 1m tail. Take this to a junction box and do a proper join to the larger cable. You are unlikely to find a variant of this connector for the larger cable.
