I created this hook to hang my backpack on the side of my chest of drawers which hasn't so much room under it.

For safety I added 2 slots for two pieces of double-sided tape; for reference for the dimensions I used the 3M VHB tape but if you have a metal desk you can also put some magnets

In the top face, I added a slot made with the dimensions of the IKEA Bintje that I use to keep my keys

I printed it standing with the tree supports enabled but if you have some problems with bridging I recommend changing to normal supports. For the best strength performance and speed, you could also print it laying down as it is in the second STL file.

I shared the IPT file so you can adjust it with the dimensions you need; I suggest not making the hook too big or the things you hang might fall
