Original didn't fit my CR10s, so I had to redesign it from scratch.

This one fits my creality cr10s, I now have a direct drive, it works, I have printed several things.

Only flaw is that I now only use one bowdentube fitting instead of the usual two (on extruder and hotend). But that doesnt cost any quality.
will have to fix this some day

In the pictures you can see the circle, which is where the bowdentube fitting is with the stock extruder on the cr10s.
