revolver pen/pencil holder for SIGNETTA pen

The model is designed with minimal support, clean look, and with big bottom surface area in mind. I used 7*22*7 bearings for the project, and I also made a model for the commonly used 608 bearings. You can also print the model without bearings. One cylinder has 6 slots for standard heyagonal pencils or signetta pens. If you want to remix the model to be suitable for other pens/pencils, or bearing types feel free to edit the .f3d file.
