While building this board, I ran into the issue of the spacebar rubbing against the case depending on where it was hit. I can’t remember which thread, but I know someone else recently mentioned their MT3 keys brushing the top part of their case. The Ikki68’s case is pretty tight around the caps, and the OA stabs let the space bar rotate juuust enough to brush it.
I got around this by doing two things; loosening the case screws and re-tightening them while pulling the front bezel away from the space bar slightly, and by carefully sanding-down the edge of the keycap.
