It is reasonably trivial to make a modified part. The existing one matches ones I bought from ebay, and in fact all the ones I looked at after typing a search for “mini 360 dc-dc” on ebay in fact show as being 17x11. If you have a pointer to the one you want I can change it easily enough. I assume you want the wider spacing on the silkscreen on pcb view (as I can’t see it mattering particularly anywhere else)?
