GPU anti-sag -remixed-

Noticed the fit was a bit loose so I made the threads on the top pillar a bit tighter. Also removed the magnet recession on the bottom piece since I didn't need it. Here it is for anyone that might want it.
97.5% gets quite tight when most of the threads are in.
If you need to have the pillars mostly collapsed, 98.5% is probably the one you want.
