You will need an M4x10mm heat-set insert, and an M4x15/16/17mm bolt.
I thought about making a print-in-place mechanism but couldn't work out how to do it without support, so just did this instead.
I think I may have lost some original parts while they were out of use, so this works with even less. Just needs the bolt that it already had.

Added another version with a higher pivot point, hopefully clear of any ribbon cable supports.
You only need either one of the clips.

Added yet another version with an even higher pivot point, surely clear of those ribbon cable sticker-upwardsers.

Added hopefully the ultimate version, with the same high pivot point but now also rounded on the bottom so even if it does contact the ribbon, it'll slide past instead of getting caught on an edge.
The author marked this model as their own original creation.
