This is my repair kit for the electric windows on the Volvo 480 that always break.
The design the same on both ends just mirrored, so you will find two files for the upper part and two for the lower part.
I might make a full replacement part in the future also but so far this has worked good for me.
Print the two parts for upper or lower end, preferably in ABS since it's supposed to be stronger than PLA.
Remove old plastic so that it looks like third picture (I also removed the last plastic part that is in the hole of the metal but have no picture of it.
Then just mount backplate and frontplate with M3 nuts and bolts
The hard part is always to get the wires back in place.
Printed part 1 and 2
2 x M3 bolts
2 x M3 nuts
No name ABS
