Monster eyes

Halloween is a favourite day of mine, so I decided to make some "Monster eyes". This is the first thing I've made in Tinkercad, so please forgive me if it's a little crude. It's designed to be taped onto a window, with the back left open, but a cover could be easily fashioned if you need one. The basic body and two lenses are included for you to glue in. The eyes are much redder than depicted in the photo.
