Ladder Box Spacer

sterbop's .308 Ladder Box (ver 2.0) and Magnum Sized Ladder Box are great! I'm new to 3D printing and haven't figured out how to modify designs like sterbop's yet. However, I was able to figure out how to make spacers to accommodate the calibers I use. The spacers are just simple tubes which are dropped into the cartridge spaces in the bullet insert. In my case, I printed one for 6.5 PRC for use in the Magnum Sized Box and one each for 6mm Dasher and 6mm Long Dasher for use in the .308 Ladder Box (ver 2.0). Maybe the best part of all is that the spacers use a lot less filament and a lot less time to print.
