Wow, I almost forgot my original Figured walnut Nano always tipped over!
My heavier (dense hardwood) Afzelia Burl Nano never tips over. I believe I requested my nano to be made a bit taller than normal with the idea of increase the weight - my current nano sits 99mm tall (3.89inch). That extra 30-40 grams of mass seems to help compensate for the stiffness of the power cord.
Yeah, it's not even anything to do with "where to put the dial" or the other solutions, just the stiffness of the cord means that sometimes I tip it over even when trying to be careful, even when there's plenty of slack. Where my dial is is stable enough for now and going to improve it at some point; but that thick cord likes to almost pull the enano over every time I touch it!
I'll probably find an old fabric/rubber mouse pad to keep it on for now, so that it doesn't matter if it does knock over. Hopefully I find something the right diameter that I can DIY myself a little stand -- as I need to replace my drill to do any serious carpentry.
The stands are nice, but I really don't want to spend the money on one that doesn't match, and then go to Snappo and Epic and try to get one made of appropriate maple burl later. Then again, at this rate, it'll be covered in dings in a year and trying to match may be pointless.
Going to have to try to pick up some of Ed's butter/wax, hoping that a coat of wax helps prevent nicks and dings.
