Should be able to just print, nothing special needed. Fit mine perfectly first try!

The pants I had were ordered online, so returning them wasn't easy. They fit perfectly except in the waist (oddly another pair of pants, different color fit perfect, this was just a weird one).

V2 has been updated, 2 versions, shorter/longer version and they are booth smooth now, so it shouldnt scrape your skin on the edges. Much better.
