was pulling the broken gen9 box apart today to sus out what’s causing the spur gear to be so tight,
turn out the bearing hole for the spur gear on the top part of the box (the ejector port side?),
is about 1mm higher than the rest, as seen in photo
i figure i could sand down the lip of it with sand paper and stuff, but how do i actually make it sit lower?
what can i use to lower it’s sitting groove? and to have it sit flat / evenly for that matter
