I've contacted Velomine and he said he'd exchange for a different one, which is good... I've already tossed my old cranks back on the bike until I get this sorted. I believe it is asymmetrical (not sure if by error or design though), spindle is longer on driveside than NDS. If it were symmetrical I think it'd fit fine, because the amount pushed out on DS would definitely make it clear NDS.
Don't think it's possible to install backwards, plus it's labelled left/right
