I used measurements from a damaged OEM part to create this printable version. I iterated through a few printed versions until I got one that worked well enough for my purposes. It's a bit finicky in that you can crack the screw posts if you're not careful with tightening it down, but there is an almost identical problem with the original part. I didn't feel like paying $20 for a part easily destroyed with the slightest overtightening, which is why this version exists. The dimensions aren't 100% perfect, but it does work well enough if you can live with a slightly loose fitment. I also included the FreeCAD project file if you want to take a stab at improving it for your needs.
