I've been looking for some kind of netting or fabric envelope that would fasten to the inside of the frunk lid and provide a convenient but out-of-the-way storage spot for my tire pump and a couple other loose items. But I hadn't found just what I was looking for so I decided to make one. It turned out pretty well
and this is how I did it.
The first problem was how to fasten the fabric/netting to the underside of the lid. My 2018 NC750XD had 4 plastic “hooks” molded into the lid … I couldn't really figure out a good way to use them as an attachment hook so decided to use them as fixed points to accept some small screws, one for each hook, plus the screw at the base of the frunk that mounts to the hinge assembly as a 5th mounting point.
(I don't think the older NC body style had these “hooks” so I don't know what to suggest if that's your case.)
CAD (cardboard-aided design) allowed me to establish the overall shape of the storage
I marked and cut the material to match the CAD shape plus some extra for a hem then stitched the netting to the material along the cardboard outline, cut off the extra netting, and hemmed over the cut edge of the net.
Note that there's a dart on the center of fabric which brings the edges of the “border” a little closer together than the original cardboard pattern. This allows the net to be stretched slightly when it's finally installed.
I then cut out the middle of the fabric, leaving enough for hemming on the back side,
which is then installed using the screws into the “hooks” I talked about above and, VOILA!
As you can probably tell, I'm no kind of dab hand with a sewing machine. If you are or know somebody who is, you'll be able to duplicate this is short order.
