This is a formula I used for getting the vent from lganderson's model to fit the scale of L3X's
*Model Height of L3X's Chest* ÷ 1.25 = *Height to scale lganderson's model*
Then simply find the pages for the vents and print only those
Just note, it may not be EXACTLY correct, I guesstimated on my own attempt and got it about right so I'd advise printing the surface of the vents on normal paper and measure it to see if it's right before you use that valuable cardstock
