Hackberry Pi CM5 stand

7th Aug - I've updated the stand with taller channels that provide more space for t-shaped usb-c connectors. I've also improved the fit of the HBP on the stand. The previous model remains as an alternative.

I wanted a basic desk stand for my Hackberry Pi, but couldn't find an existing model so I made one. I created a taller version of this stand [on it's own Thingiverse page](https://www.thingiverse.com/thing:7103998)
