I've already printed mine out. It's been a little trickier than I first imagined.
Even though the template would easily fit on a regular sheet of paper, I can't seem to figure out how to adjust my margins on the Acrobat file to get it to print out the entire 2nd page. I finally got a sheet that was only missing about 1/2", and I was able to draw in the missing bits. If you don't print it the right size then a 35mm cassette won't fit.
So then I started cutting it out with an X-acto knife. There are some complicated pieces here, and the assembly instructions in English aren't making much more sense than the ones in Czech.
Well, I have mine half cut out, and I've managed to find my roll of gaffer tape, so I'll try to figure it out.
