In the past, I've always used 0.1" width joints between boards I want to have assembled and then broken off. But just got a board rejected by JLCPCB saying they now want 3mm minimum. So this led me to thinking about V-cuts. Surprisingly I've never used them before (in almost 50 years) so can anybody comment on what they look like aestheticly vs the usual joints after a quick sand down, especially when used for front panels where the user can see them constantly ?
Brand new interactions and interfaces. 
Easy to use and quick to get started.
