Hi.
I don't know, who like this, but for me, this upgrade is very helpfull. Because when I try to tighten a screw (on the downside location, holding extruder in one positon on piece of metal frame) I can't do this enought good. All block with motor and extruder was turned sideways. So, I think. And If to block this with another method? Without screw, glue, or duck tape :)
If You have the same problem, U see the very easy solution :)
