They shouldn't even sell this bad 3D prints made on a cheap 3D printer...
My brother-in-law has a nice 3D printer that cost more than 1000€, I have seen some small testing stuff he did and prints well, but I won't even bother him to make me one...
When Atmosphere come, I will open the joy-con, connect a cable from the 10 pin and touch the Switch cooling fins which are grounded, that is if when they release it could coldboot, else I would rather add a button on my joy-con.
I have everything I need, but nothing that got released still make me want to test, if we could boot android then I would test it right away... I will just wait for atmosphere and then also do some extreme cooling mods on mine...
