And that includes also shielding Jolla GSM+Wifi+BT antennas? Hmm...
So I'm pretty sure it will not make a difference.

Although, I'm not sure if having bare magnets on the backside will attract random metal objects nearby. Every once in a while you'd have to brush staple pins and paperclips off your pocket
Possibly a stupid idea:

Use some crazy glue to hold the magnet in place. This way the magnet is closer to the other-other half and the wood covers the whole back side (thus distancing magnets from attracting paperclips).

maybe i missed something...
well i certainly did as i didn't follow this thread for weeks but...
my understanding is that the wooden cover comes on the bottom of the actual keyboard part (the side which is mostly visible when the keyboard is not used)
why do the magnets have to be on the bottom if they should attach to the magnets of the Jolla backside (the upside of the keyboard, right?)?!?

Hmhmh. I played around with Sketchup, but I suppose I'm fine with the rounded cutouts in the wood for the two magnets. I do really like the third one, as the wood is slightly less overwhelming (exhibit A, B), but it'd obviously be significantly harder to do so not feasible.
Then again, the grey wood ("kelo") is more subtle, both on white and black keyboard pieces.

I just want to say that I fully trust dirks experience and judgement.
From what I understand from following this thread, he made extensive and thorough R&D to come up with the project as it is.
Changing the position of the magnets may appear simple but, e.g., adding new components (like glue, epoxy, ...) and the combinations of the components (cover <-> glue <-> magnet) imho add significant error potential and would require to repeat quite a lot of R&D or even longer additional testing.
Similarly, injection molding may sound cool. But there are many uncertainties as well, e.g., the molding process may vary, the molding tools may not fit on the first try, or the quality of the material may not match the expectations.
Furthermore, the costs for iterations in molding, e.g., when the tools have to be changed are in the magnitude of thousands of euros compared to about tens of euros for 3D-printed parts. Plus the advantage dirk mentioned that the 3D-printed parts can be re-ordered by anyone who has access to the respective files.
Last but not least, the backers at kickstarter had a very good overview to know what they subscribe to. Changing this afterwards could be problematic and may lead to frustration and disagreement.

Oh why not? After seeing the sketches I like it even more. How about a poll?
