holder for 6 nespresso cartons, easy to modify for more or less cartons. After opening the carton cut off the lid... I took about 3 itterations to find the good inside shape for pushing the cups out but now it works perfect. I enclosed the .rsdoc file so you can easily modify with the free "Design Spark Mechanical" software. The file also contains the single version, so you can easily create different versions for different quantities. download DSP; http://www.rs-online.com/designspark/electronics/eng/page/mechanicalSettings for my print (about 21 hrs) Cura 14.01 Layer 0.2 fill 25% Speed 35 mm/s
