Desktop Mouse Stand

I designed this stand for my friend who has multiple wireless gaming mice (different ones for different types of games) so that he has a minimal way to keep his mice at the ready while also showcasing them on his battlestation. Designed to hold most wireless and wired gaming mice without any plastic touching the bottom sensor. 

I am just learning how to design 3d models and this is one of my very first designs, so any feedback is appreciated!

Printed in PLA with 3 walls at 20% infill, but you can print it however you like. Supports are not needed.
