Bluescsi Macintosh SE Bracket

I was looking for a suitable holder for my bluescsi board (ver 1.1) in my macintosh se, yet without any success. So I quickly sketched this bracket which fits both my macintosh and my bluescsi perfectly.

No need to open the macintosh to replace the sd-card. For my own use I printed a half-aa battery holder onto the bracket, so that I can access both the battery and the sd card without opening the mac. And the expansion slot cover still closes properly. For anybody interested, I can share that file too.
