Ladder Hanger / Hook

Printed as oriented (see photos / STL file), it doesn't require support and the dual orientation (horizontal and vertical) of the hook and washer combo creates a lot of strength at the mounting point. The hole through the washer is 8mm, which easily fit what seemed to me to be a plenty strong screw.

Each hanger (you'll need two for each ladder) needs two washers.

I printed with 5 walls and 20% infill; the resulting part feels super strong and rigid. Probably (like the design) overkill but that's generally how I roll.

Don't overtighten the screws; this design is reasonably resilient to tight screwing (ooh-er) but not impervious.

You'll note that I'm largely theoretical with my description; when mounting mine i may or may not have drilled my screw holes into the back of my electrical panel and needed to pay an emergency sunday electrician to get power back to my house, putting me off using them as planned. Allegedly. Ahem.

Anyway, they're super strong with a ladder gap of 160mm, which is more than enough for my 6 foot ladder.

Please let me know if you have any requests (such as a different sized gap, screw spacing, witdth, etc) or any feedback that might improve a future revision.
