FT CAD Gremlin
Looking at the PDF it looks the same as the CAD file to me? Did your printer maybe have an issue?I'll have to look at it when i get home.
The image you uploaded is a bit different from my plan. On my copy, the short and long ends are straight up and down at 90° to the bottom of page. It looked skewed, so I traced it and that's how I saw that it was off by 5mm on the wide end. I will recheck when I get home.
