This Instructables shows you how to 3D-print a mixer.
Step 1: Print the Parts
Get the file and convert it into G-Code with your favorite Slicer (for example Cura or Slic3r). If you don't have a powder printer you should split up the Mixer into it's parts. Simply do that in Cura or Slic3r by rightclicking the part or going to the object informations category and click Split up.
Now you have the parts separated.
I printed my mixer on a K8200 (also known as 3Drag), which is a low to medium quality printer.
I used Red PLA and a layer height of 0,2mm.
Step 2: Put the Parts Together
Take some glue and put the parts into the holes.
After the glue dried, you can click them into their places and start mixing!
Step 3: Some Words About Food Safety
Although PLA consists of plants, it is not completely food safe. This is, because arrears from the catalyst used during the production, can remain in the plastic.
