Vertical Stand for CISCO 800 Series Routers

This is my first design of a vertical stand for Cisco 800 Series routers.
The manufacturer does not offer such accessories, so I decided to design one myself.
The inner dimension of the width is 46 mm. The router's height is 44 mm without the rubber feet so I hope it fits.

Update Version V2:
Here's a new, lighter version of the Cisco 800 Series vertical stand. Now, the big pillars are much higher to provide more stability and I´ve added 4 mm holes to fix the router with screws or somethin
