I added a 2nd set of washers to my assembly, I noticed that there could be vertical wobble since there IS 2.75mm gap between the pcb and the insert, so I reduced that to .75mm (basically nothing). That way, the pcb is kinda sandwiched between the spacers.

Also another thing, for some reason my hackatime timed sessions are around 10-20 min slonger than the lapse one, which I find weird! I asked in slack but they told me there is nothing to do about it.
