Designed hooks to mount a ladder horizontally on the wall, the goal was plenty of strength for a folding aluminum ladder and a sleek look with clean lines. Two lengths are included as I found the two ends of my ladder needed different depths and I wanted them to be otherwise identical. When setting up to mount a ladder I suggest pressing it up against the wall and measuring before printing anything, the folding mechanism/small shelf may add some width you would otherwise not take into account.

I found that loading and unloading the ladder led to quite a big of banging around that could potentially snap the end off, so the last ~20mm at the tip has 60% infill and extra thick walls for strength. Scaling the Y axis within reason shouldn't be a problem.
