Know of a good simple 3D gui blueprint design?

Hi All,

I’m starting to use and expand my own simple little 3D gui design for my VR game but before I get too far I thought I’d ask if anyone knew of a good simple design that was available for free or not expensive that I could look at and steal some ideas from?

I meant the technical/engineering design of it.

I am using things like buttons, text fields, editable text fields, a keyboard, confirmation dialog, text panels.
