Unfortunately I don't have pictures of the bayonet ring before attachment but here is a (rather bad) picture of it without the lens. It's screwed on so it can be removed and exchanged if I were to buy another kind of lens.
It was quite tedious work to carve the thing but the lens does fit quite perfectly now.
I still have some problems with the internal flash creating reflexions from the WA lens. I'm using the black rubber tube that was originally in the housing to shield, but I also need to put some tape inside the port.
The acrylic is 5mm thick.
