Fujifilm X-T30 cameras and alike EVF adapter for Magnifying Eyepiece

Great stuff, and I look forward to trying this out! One recommendation: for someone new to your design, a description of the assembly per combination would help. From what I understand, there's currently three versions:
1. Solid
2. Hinged
3. Locked

If you could list the combinations of parts for each of those and how they are assembled, that'd be very helpful (e.g. "for the solid version, you need to print these parts and assemble in this order").

Thanks for your work! (edited)
