Pen Plotter Adapter for Vevor Plotter

I made a quick pen plotter adapter for the white and blue vevor plotters. Its large enough to fit a sharpie and any smaller writing instruments you might want. The holes on the plotter adapter are sized for an M4 screw but the fit is quite tight, I would recommend using a threaded insert here if you'll be changing the pen out frequently. I also added a relief into the hole on the top side so the original blade holder fits if you wanted to do a draw and cut operation.

** Important to note that the blade holder MUST BE REMOVED on initial start up or the carrier head will crash into the side of the plotter due to the extra width of the adapter. The limit switch on my particular plotter is a magnetic reed switch so I was able to install a piece of metal inside the plotter that will stop the carriage short of the plotter side wall. I've also removed the top decorative panel on my particular plotter to allow taller pens and pencils to fit.
