I needed a quick solution to organize my devices while charging, but with the weird mix and quantity of devices I use on a daily basis there was really nothing I could just use.
Therefore I created this fully customizable model, that really does need customization to be useful to you also. You can change this model to create an organizer for any combination of devices that you need, or to hold your toast if you wish. All you need to do is edit the list of walls and bridges in the code editor in the customizer to define how wide each slot should be and how high each wall. MakerLab unfortunately doesn't quite allow all arrays yet in the customizable parameters. After having defined this, you can change the basic parameters of the model.
Although I don't like the clean-up, I tend to print this with a brim so I am sure the model sticks to the build plate properly.
