"Low effort silicone bed leveling mod" for the Mini.
I had some very slight issues with first layer consistency on my Mini, like a few tenths of a mm of here and there. Prusa says you can try and fix it by loosening/tightening the bed screws, but that still didn't get me all the way.
I had some 6 mm silicone tubing laying around, but didn't outright want to do the full silicone mod. Since it was just a few tenths I thought, what if I just put some tubing around the existing nuts? So I cut off some 6.5 mm long pieces (7 mm might also work, the offsets are 6 mm) and lo and behold, it did the job. Obviously this only works up to about a mm I recon, due to the length of the screws that hold the bed, and I don't know if it will hold up. It at least is a lot less involved than the full blown mod.
Tl;dr: I put some pieces of silicone tubing around the existing standoffs to correct for a few tenths of a mm.
edit: a tube length of 7 mm seems to work a bit better than the 6.5 mm I had at first.

Interesting. How many did you do this on? Did you remove the whole bed to do a few of the screws?
I put them on all of the standoffs. You do need to take off the whole bed, but this takes only a few seconds.
