anyone else having trouble with the customizer? It seems there is a ASCII/UTF-8 conversion problem (maybe the (C) symbol.)

I printed one of the stock ones and it looks great! Going to tweak for some 1" nails I have a bunch of.
As others suggested, I spread some hot inside the "broom hole" to provide a grippy surface and prevent slipping. Worked great.
