Repairing my keyboard was annoying because the pressed keys would pop out the plastic pieces. This stand/jig screws into the keyboard top allowing the keys to hang free so you can easily reassembly the keyboard without the plastic "springs" popping out.
When re-attaching the (up facing) keyboard bottom, I attached the center screws. My small screwdriver was able to extend through the bottom and loosen the screw holding the stand/jig in. I was then able to remove it from the keyboard and attach the screw through the bottom. I then attached that side's screws and repeated it on the other side.
(This sounds more complicated than it was!)
I printed with 4 perimeters both to speed up the print and make it stronger. I used 0.3mm draft mode layers with a 0.2mm nozzle. Vertical quality really doesn't matter.
You need to print two of course.
