Echo dot gen 3 holder

Remix of https://www.thingiverse.com/thing:3369130, i added the space on the sides of the mount so the power adapter can be installed with the prongs horizontal or vertical.

I did this because i had an outlet that was horizontal and the existing mount only supports the prongs on the power adapter facing vertical

(this works perfect for the Echo Dot 3rd Generation, I purchased the Echo Dot in the United states, not to sure if itll work with the power adapters from other countries)
