I drew some up back in 2017 and had 3D SLS printed in nylon for my own wagon... things have held up well. These replace the rubber covered bits that are NLA new. It seems I have sold a few thru my Shapeways shop over the years they have been up:

If anyone here has bought some let me know how they have held up for you. I adjusted with shims so they nearly touch the aluminum receiver on body when hatch closed. I have noticed no squeaks or rattles from my hatch and the printed parts have not cracked but I do see some scuffing on the surface. Best to order these in black dyed nylon (Black Natural Versatile Plastic)

I also drew the Rear Wiper Cover on the hatch. I printed in White Versatile Plastic and painted with SEM Palomino spray to match my interior.
