Some of the references above will not fit in the Non LP 2011 OG Mini the OP is asking about. FWIW...
Nuppin' ... LP Reos.
The OG Mini will not accept atty's larger than 13.2mm (a tight fit) unless someone had Rob or somebody else enlarged the drip well, or shaved the deck to LP. IE, my ERA will not fit in my OG Mini, nor will a Cyclone or an IGO-S because they are all much larger than 13.2mm. A Chalice will not fit them either. A standard RM2 (non LP) will fit the OG Mini but looks kind of strange. The Hornet, Mini A7, probably No Name has a bf something that will, and there may be other bf atty's that will.
There were only a few Mini 1.0's in this last run that were not LP. If the well on them is the same size as on the LP version though they too will only accept the same 13.2mm atty's that the OG Mini accepts. On the LP version atty's up to about 15.3mm will not overhang the deck.
The standard Mini 2.1 (non LP) will accept atty's up to 15.2mm.
