About this 3D model

My friend Zak designed this on Google Sketchup as a calibration print and a little project we are working on. Works very well! Printed with no raft and came out beautifully after I tweaked some settings (I just upgraded to MK6 and Gen 4 Electronics on my Cupcake #65!!). Holds 1.5 ounces and is waterproof...enjoy :)
