It might be best to measure the nuts you have or will be using. AFAIK there's no standard for the slots. I'd hate to make a wrench based on someone's dimensions & then possibly find out that it doesn't fit my nuts well.

I have various ER40 nuts both in bearing type & standard type from various manufacturers and they all differ slightly in width & depth. I've even had to modify some of my wrenches to fit my bearing nuts.

But aside from all that, I don't have any ER32 stuff. Hopefully a number of people could post dimensions from different nuts & you can average it.
 
In case anyone is interested, Fastenal is selling Techniks INC ER32 collets for $12.49 each.
 
Google is your friend. Search "er32 dimensions", use image search to narrow it down.
