Sturdy Backpack Hook

Was cleaning my man cave and wanted a place to hang my backpack/laptop bag that can easily have over 20 pounds between work laptop, personal laptop, iPad Pro, charging cables, calculators, school books, etc. This is what I came up with. I didn't check the actual weight, but I put some of my bodyweight on it and it seemed fine.

Had a box of these [wall anchors] (https://www.homedepot.com/p/E-Z-Ancor-Twist-N-Lock-75-lb-Medium-Duty-Drywall-Anchors-50-Pack-25310/100040265) sitting around, so this hook is designed to work with those screws. The Home Depot page says that it's a #8 x 1-5/8 in. screw.

I recommend putting extra walls and top/bottom layers and printing at 20% infill for extra strength. I went with 1.6 mm walls and 1.2 mm top/bottom layers and 20% triangle infill in Cura.
