Pen Plotter Mount

The pen plotter mount by Fizzy Chickens wouldn't mount tightly using the spare hole (and spare bolt that comes with the printer) as the bolt bottoms out as pointed out by switchboard.op . Their remix added a small ring around the mounting hole as a spacer, but I found this to be less than effective as it reduces the friction area of the two mounting surfaces. I've achieved the same thing but by increasing the entire overall width of the mounting plate. This lets you tighten the bolt without bottoming out, but with two large solid faces pulled tightly for a snug friction fit.
