Collection of tips and fixes

So i got my nano and i noticed there are some small quirks like the z motor needs a lot of rings to be correct.

So i figured that a collection of the small fixable things might be handy.

This is meant to be a community effort
So please if you know a tip trick or fix post it here please.

For imprpving print quality a part cooling fan is a good improvement there are 2 on thingiverse and im working on my own version.

Just a 30 mm fan can be spliced into the hotend fan no problem.

I hope to see more tips appearing here
