There are two ways of doing it.
one is using the DK3, square to round adaptor and an eyepiece replacement for fm2/fe:

which is what i'm using now. square to round adaptor is available at alex photo.
altho' the price is a bit ex. so, just get the square to round adaptor, can get the rest(DK3,eyepiece replacement for fe/fm2) at CP... cheaper that way.
The other cheaper option is using DK6 and filing it square to fit the D100/F80:
