Makerbot sells a box for $95, but it sounded expensive for a box.  I think my solution will total less than $8 (at the most) and sit neatly on top of my MakerBot.  Keeping things simple and compact as possible were my priorities.  I love that Mendel parts will be feeding the MakerBot!  I will post a pic when it is finished and mounted.  Filament issues have caused many failed prints.  I have not seen anyone use this simple approach on the CupCake yet…. send me pics if you have!
