3D printing a fidget spinner

This video shows the process of 3D printing and assembling a fidget spinner. I have designed the spinner using Autodesk Inventor. The spinner is slightly asymmetric, making it easy and comfortable to start it. I use a ceramic ball bearing in the centre and normal bearings as weights. I always use Cura to slice my parts before 3D printing. To print in different colors, I manually edit the generated G-code file using Notepad++. Cura automaticly puts a comment in the G-code file at the start of each new layer. I use the search function to find a specific layer and insert a couple commands to lower the printbed and pause the machine so I can change the filament.

The STL files for the spinner is available on Thingiverse here.
