tom did a video of why those feet are bad and can cause ridiculous slop in certain printing patterns. i went to home depot and got a rubber backyard paver for 6$ and it's perfect for dampening sound and not causing resonant vibrations.
additionally using these holders for these [polymer linear bearings] (https://www.amazon.com/gp/product/B071RSDYW4/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1) removes the problem of over-tightening the bearings and will be much nicer and last longer than 3d printed bearings.
With the solid bearings, the rubber paver and the noctua 40mm extruder fan mods the mks2 is exceptionally quiet. the only sound issue i have now is some chirping/squeaking from the extruder bearing when doing very small rapid infill.
I would order this:

Also you shouldn't need the usbasp unless you want to flash the micro version of Marlin as that requires a different bootloader. The regular version you can flash with just a USB cable (which is what I did).
