Sainsmart Genmitsu Pen Plotter 65mm spindle mount

I got a pen plotter from Genmitsu but I don't want to remove my spindle to use the pen plotter so I designed a mount that attaches to a 65mm Spindle and holds the pen plotter in place. 

You will need 2 x M4 Nuts and 2 x M4 x10mm Bolts to put the mount together. 

I will release an 80mm version as well but I don't have an 80mm spindle to test.
