I haven't found a standart 70mm hub adapter with a fitting DIN 6 Pin Connector Housing for the ones i bought on AliExpress, so i made my own. Hope this helps you if you had the same Problem.

I used the threaded part from Slowly, the rest is build on my own.

The 2 Holes in the middle part of the hub adapter are for M3 threaded inserts.

I recommend to print the threaded part of the hub adapter as well as the DIN Connector housing with 100% infill, as it's already pretty small, the threaded part of the hub adapter.

There are clearences in the holes for the nuts and screws etc. already build in, so there shouldn't be any problems there.

The 6 Pin DIN Connector i used: https://de.aliexpress.com/item/4000139817115.html?spm=a2g0s.9042311.0.0.24c24c4dmZUAV6
