I normally publish and update all my models at MakerWorld. They are only here on Printables to keep the accounts consistent.

Please download the newest version here at MakerWorld.

There are a lot of desk hook models here. They look great, but they were all too big or too sharp for me.

So I made my own. It is designed for board thickness up to 24mm. I you need it bigger just scale it up in x and y.

I had best results in printing in PLA with 6 walls, 10 top and bottom layers and 25% hexagon infill. No support needed.

ABS, PETG and ASA also worked well, even when printed less massive.
