Agree with Frc - Fusion 360 is great once you get the hang of it. Its actually not dissimilar to using Sketchup, with the difference being you can create a sketch like a piece of virtual 2D paper anywhere in 3D space and then start extruding shapes from those (or cutting/combining etc.).
It also includes Meshmixer within the app now, so you can go from scanned objects and STLs etc into the parametric workspace easily. You can also get Fusion to call Cura or another slicer app and it automatically sends that the model you have selected, which speeds up the workflow no end.
Oh and you can share your projects with other Fusion 360 users and branch/merge versions like you would software development.
Back on topic - I’d also be very interested in playing with the CAD files for the 8K if only to make a new compatible HMD rest/stand like I did for my Rift.
