Has anyone tried the 35mm "jack-up"

so to speak in their holga?
I love the look because of the neat sprocket holes.. lots of examples on flickr of course:

I'm trying a couple rolls today and seeing how they turn out. I used foam to fit the 35mm canister, then rubberbands around the uptake spool (?)... like this:
