Pine64 - splitted case [needs help, better design]

This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/bSGCw3cvhRR

Hi,
I've used two designs for Pine64 case as I have a M3D printer that can't print anything larger then 10cm, so I needed to split the case...

Now, I give the community the idea for the case, and expecting some help from better designers to make this case available and functional for everyone :)
