Pen Plotter

I wanted to get a little more familiar with CNC functionality and GRBL so I decided to make a pen plotter. Most of the parts were designed by through trial and error but a few pieces are modified versions of other thingiverse authors.

The belt clamp has been modified to have a 5mm hole to allow for a recessed M3 fitting.
The Z Axis pieces and pen holder are modified from user henryarnald's corexy design found here https://www.thingiverse.com/thing:2349232

Print parts at 75% infill or higher, or you may run into some shear issues.

Here is a generic BOM https://docs.google.com/spreadsheets/d/1DXzxWyq7gYKpErp6kOxZUvcJYln6Au--C5VUBMZGZWc/edit?usp=sharing
