Some of you may not know this, but if you have a Replicator 1 3D printer, there's a 3D model that gets loaded around your build plate.
Pretty nifty, no? Well, it turns out you can do this for any 3D printer, but the making the change perminant is... painful.
It seems there's a menu option for this under Tools->Machine Options->Add Model, but it doesn't get associated with the machine settings and so it disappears the next time.
First thing, this needs to be fixed. Next, Simplify3D needs more 3D models of printers. This is a "wow" feature that no one else has and everyone I've shown it to wants.
