Just X it out and click download again. Both are one to one scale and save in pdf file. Please select actual size when printing. The print will be exactly one to one scale. There is a ruler on the artwork for checking the accuracy of your printer. The exact measurement on the width of the chassis is 76mm or 2.99213 inch. When you place a ruler over the artwork ruler, it should match exactly and precisely.

I did a short chassis in 1/8 or 0.125 inch G10 FR4 black fiberglass plate with just some basics hand tools no CNC.

Here are some links for ordering fiberglass plate in Canada and the US:

1/8 or 0.125 inch is the standard thickness for Butterfly chassis. I order two 12 x 12 inches from eplastics. One black and one natural. Each plate is enough for making 2 chassis It seems eplastics has the best price. Make sure you ask for a shipping quote before you place your order.
Here is what it looks like on my custom Ford F150 Ranger XLT.
