RC Adjuster Wrench

I recently built a new RC car, and thought a tool would make installing rod ends much easier...
This one has a 4mm and a 5.5mm slot, which will probably fit most 1/10 scale on- and offroad cars (and if it doesn't: it's customizable, so you can make it fit your own car :) ).
Update 2020-06-15: Added 4.5 and 6.0mm.
