Qube 500 GPU support

As the introduction describes, this is my attempt to create a matching support for a GPU for the Cooler Master Cube 500 case. It is designed specifically for the XFX Radeon 6700 XT SWFT 309 but it might fit other (XFX) GPU's as well. 

As long as the edge of the PCB is exposed somewhere (and preferably combined with the metal plate), there is a chance that it will fit. The height is probably pretty accurate, since the PCB itself is always at the same height from the bottom of the case since this is always aligned with the PCIE slot. 

I've also added a second model. This is for bigger cards with the edge of the PCB and metal plate exposed. Haven't tried it since buying GPU's for testing purposes is a sure way to get yourself broke. 

And if all else fails, I've also included a third model to support the fan cover from the bottom (I don't like that because it is less pretty). I've included the FreeCAD files so you can tinker with it yourself. It is parametric and the height of the support arm is easily modified by just changing the dimensions in the sketch.

There are two screw holes in the bottom. Note that the bottom plate has a slight height difference. This is because of the screw mount slot in the bottom of the Qube 500 for the 120 mm fans. One of the screws goes into this slot, the other into the mesh of the panel. Use generic small self tapping screws with some washers if needed.

Printed in PETG on a Prusa Mini+. Make sure that you set the perimeter value at a minimum of 4 so it doesn't fill in all the tiny spaces in between. 

P.s.: whatever you do, make sure you are not knocking off any surface mount components from the edge of the PCB! Look carefully where the mount can be placed before you end up with a broken GPU. And don't force anything.
