GPU - Graphics card support post system

One of my PC GPU's (graphics card) was misbehaving and I realized the power supply cables were dragging it down so modeled this system to enable me to prop it up - A lot of these commercial posts are quite small but I designed this so it's flexible and in my case I use a number of posts to support the GPU from the floor of the PC case - it works!
The thread is a coarse 6mm and I tend to run a tap and die over the printed parts but that isn't really necessary and they do work fine
