Ladder bracket

I printed the wider one without considering that the ladder needs more points of support to prevent it from moving if someone stumbles on it. So, I made a version that is half the size. Two of these would need to be used to hang the ladder. Choose whichever you prefer. 
Side support part is optional.

I used 3.5 x 20 chipboard screws.
