Prusa i3 multi material tower brim

Printing this with a skirt is not advised as it will print the skirt on the outside perimeter of the print bed.

Having a heck of a time keeping my waste tower from lifting from the bed, even with glue, so until Prusa updates Sli3rPE to allow for custom brim settings for the tower itself, I designed an STL overlay to create an addition 3mm fileted brim for me. It is designed to print around the 60x15N tower and help hold it in place. You'll have to assign the STL to print in whatever color the first layer of the tower would otherwise print in (check the preview in Slic3rPE!) but then it should just work.

Please note the large cross (which should be too thin to print by default) is for exactly placing the brim without having to do anything but move the tower origin itself to 180mm X and 155mm Y, using the default width of 60mm. For whatever reason, the default tower, which can be no larger than 60x45, is placed 70mm from the right side and 70mm from the top, leaving a whole 15mm of
