Zyxel LTE3301-PLUS Router 4G Modem Wall Hanger Adapter

LTE Indoor Router - Zyxel LTE3301-PLUS 

The Router has mounting holes on left and right and manufacturer do not sell mounting brackets for it.
I wanted to mount it on vertical space - so i designed little brackets for it. 
You only need to find matching screws for the router - scrap from old laptop for part out
