Glue gun stand fixed

This is a remix of https://www.thingiverse.com/thing:250787 by Matador.

The model was showing a hole in Cura where the gun would be, but the print was filling that hole in. Took it into Mesh Mixer, made it solid (which then showed the hole filled like it was printing), then made a rectangle and Boolean subtracted the shape to remake the hole to resemble the original. My version is a much bigger .stl filesize but it printed correctly for me where the original did not. As Matador said in his description and comments the problem might be which slicer and whatnot, but seeing as I use one that seemed to have a problem I figured this might help others in the same boat.
