Gorilla glue assistance.

I completed my Landspeeder and glued it to the clear plastic stand they provide in the box. I supported it for a day or so as it dried and it looked fine.

However, over the next couple days it started leaning back a little further each day, so much so that it annoys me. It seems to have fully dried now, as it doesn't move when I bend the flight stand.

Anyways to easily remove it? Chemical? Cold? Tips appreciated!
