My first ever CAD design, done in tinkercad at my desk in the office building. The standard cubicle attachment coathangers were out of stock online, so I decided to actually put my 3D printer to use for more than just fun little trinkets and benchy's. As you can see from the images, it easily holds my 25 lbs (~11 kg) backpack.
