This is a simple but effective mini-shelf to allow small items to be charged directly on top of a mains-outlet-based USB power socket.
It won't take anything huge due to the weight limitations on the socket. However, for small items it works very well. A 20-25mm charging cable works well.
I am very much an enthusiastic amateur when it comes to designing. My designs tend to have two things in common
1) They serve a purpose. I like to design functional objects which have a real-world use. 3D printing for art is fine, but it's its real-world application which will take the technology forward
2) Wherever possible I design to be easy to print and try to eschew supports or complex printing; modifying the design where necessary and possible to achieve this.
