I needed something to hold my window open when the wind blows so it doesn't slam shut. I found very few of these around. Or that were fully made out of plastic, which is fine, but id rather have metal bearing components.
Total height: 44mm closed, 70+ open.
Requires an M4x36mm Bolt (shorter can work, however this reduces the max reach of the jack) 35mm seems more common.
An M4 heated thread insert
For making a lot i reccomend buying some M4 nuts and an M4 threaded rod. And using some glue/epoxy or welding the head on to attach it.
I use this jackscrew for my window, propping stuff up, and a PC GPU stand.
Step files provided soon, if you wanna make adjustments.
