Process

For this project, I started by initially measuring the diameter of my pens and pencils with a caliper. From here, I rounded up the size of the diameter to give the pens/pencils a little extra wiggle room in their holes. 

I then created a sketch in Fusion360, extruded the sketch, and exported it as an STL file.

From here, I used Zortrax to upload my STL files and arranged them on the 3D printing platform. I set the print options to medium infill and high quality. I then borrowed an SD card from the lending desk, exported my files onto the SD card, and printed the files on the Zortrax M200 machine.

Initially, I had issues extruding the holes for the pens/pencils. So I ultimately had to extrude the initial cylinder, and then from here I created a pattern and extruded the holes for the pens/pencils as well as the hollow core.
