Yes I will share on this sub. Since you are interested though you are welcome take a look at my github early. Added a 3x5 version of the case there as well (not tested printing).
Hand-wiring shouldn't be much more difficult than my first build with per key pcbs. It is pretty thin though and assembly will be a bit tricky regardless of how it's wired. For printing I've only tried with MJF and SLS and I didn't really take into consideration any limitations of Resin or FDM printing. I don't think there is anything that would make printing any of the parts with those techniques (though maybe some parts are a little thin for FDM) so keep that in mind.
