The V1 and V2 are not that different, they have the same key layout, but V2 has a lot of minor improvements, so I suggest building that!
Here are some V1 images:

Probably the cheapest tenting solution: https://www.reddit.com/r/ErgoMechKeyboards/comments/16s3yb2/cheapino/
@keyboard-magpie made a plate which will help position the switches: plate.stl
@ggppjj made some useful modifications to miryoku and enabled LED for that as well here: https://github.com/ggppjj/qmk_firmware/releases
Drawbacks:
- V1 only: Without a plate, its pretty difficult to solder swithes straight. I made a small helper "fork" to hold each column in place when soldering. Check the build guide for a link to a really good 3D printed fork.
- RJ45 cables are a bit rigid, so they do not lay down on the table nicely like audio cables.
- There is no official qmk support, you need to compile from my branch manually... Keymap can be edited in qmk configurator though.
