printing WOF Jetpack templates on A3 size

Hi guys,
I tried numerous times to print the great looking and multiply used WOF templates (PDF-file of 57 pages) of the sticky thread here. http://www.thedentedhelmet.com/f20/...-7559/index5.html?highlight=wof+jetpack+print

I cant seem to print them out on A4 (or A3, which I can also do). Keeping them on actual size or changing it to Letter (8.5x11) makes them too small, or too big), any suggestions or alternative files/location where I can get them on right studio size prints (16,5 406-419 mm?)

Thanks guys

Got most of them converted to A3 size, some of the WOF template on letter size are now combined togeher. Cant thank the wizzard Alan enough! Great work for the community. Used the measurements of this pic I found here somewhere as well for reference Some are 1mm off but this is also the thickness of the cutting line. Maybe someone can doublecheck them?
