Hello again everyone! I was recently told I made my box too small for the Straight through setup, and that I should look to Folded, bassically I have a box that is 18x15 and 31 Inches Long, does this seem like an acceptable length for A Folded Design w/ A DIYPC Long Throw Lense?

I have a sugestion for you my box was to short also so I made my focus box longer to add the lengh that you need and slide the hole thing for your focus

Right Now I have a Box that's 31" Long, I really don't want to trash the box, And have heard about the possibility of folding, Does anyone think that 31" Is sufficiant enough for my setup? I could do your Idea too magel if worst comes to worst thanks for the idea, I didnt think of it
