Flux Delta spool bottom

Designed to cover the hole in the bottom of the spool area. This is useful if you have a spool that doesn't lay flat in the spool area, and need to be able to put a spool stand in the same area.

I'm new to 3D printing, and this is my first model. I had some pretty bad plate adhesion problems when printing this. If you can tell me how to save the STL file so that it is 160mm wide, that would be helpful.
