i made several difusers for the D2000 and Z240.
You need to make holes for the focus light and the light sensor as on the original diffuser.
I used:
- milky acrylic sheet (perspex/acrylic glass) cut round and drilled holes for the screws and the light sensor/focus light
- various milk/tupperware plastic disks
- white baby socks, nylons and white plastic shopping bags (stitched on a thin bungee cord to hold it over the strobe)
Perspex worked best and is in various types/thickness/texture available but need medium DYS skills to saw/drill it and a place to find
the right screws.
Milk/tupperware worked less good, but are more simple to shape and cheap
Socks, nylons and plastic bags work "not bad" and are easy to assemble and un/mount but look "unprofessional"
The screws are M4 or M3 metric treads, i found them here in Italy and we have no imperial treads in Europe.
A bigger hardware shop should carry them, if not in SS get them in brass or steel and change them frequently.
