modern shelf with cable management (for Echo and more)

IMPORTANT!

I updated the design with hidden screws and a french cleat system to attach it to the wall. 

Your feedback is highly appreciated:  Here is the new model

---

I did not find any model for my amazon echo and I wanted something which is simple, but also modern looking with round elements. 

I came up with this design and built it from scratch. I included a cable guid from the back which fits perfectly for the echo power plug. That way the cable will stay in place even if u detach the device. 

It is printable without any support. I used 20% infill. It's pretty stable and looks awesome on the wall.
