Sorry this is so late, and thank you for your replies!!! My MacBook won't go beyond OS X Yosemite and Cura needs a later operating system to run nowadays, so I am stuck with Slic3r for a while. I like your MeshMixer trick, never thought of that but I'll try that next time the same problem crops up. Going to download your new Voice Light file now and try it. I'll let you know how it works out. You did an awesome job on the whole design! Thanks!!!
*** Edit - Ok, you are the SliceMaster! Slic3r gobbled it up and spit out gcode wihout a hitch. Tomorrow I print! Once more, many Thanks!
