I made a sloppy remix in tinkercad to use it for the basic(red) double-gear extruder as the passthrough hole for the filament is 1.4mm higher than on the standard one.
I had no chance to print it jet. Will update asap.
Extruder looks like this one: https://m.media-amazon.com/images/I/71wkeFuHsZL._SX342_.jpg

I finally got around to printing out the 2nd Version of this as the 1st one had some flaws.
A chamfer in the front-facing plane for the cable that comes out of the head for it not being too clamped. And the second change is that I left a hole so that the score for the fan cover can be screwed back in
