Hi there!
I am 46
and I start having problems working with very small parts, the Dnano front spring being the ultimate challenge and if ever these will fall to my carpet floor i would normally feel bad.
But do you know what? I don't care
I made myself the ultimate tool:
These are basically 4 office type magnets taped together. They are foldable so I can put them in my Dnano parts box and to top it all, it will magnetize my screwdriver. Until now I never lost any screw, a spring or any mini RC metal part. It is just a matter of scanning the floor slowly and you can hear a click when the part hits the magnet
@Lornecherry: cool tip but on my Murcielago the knuckle would disassemble without this mod, I just need to steer to the max left or right and it clears away.
