Air box mounting bracket for XJ900

My recently acquired 1983 XJ900 was missing the bracket that bolts the airbox to the frame. I found some used ones on eBay, but they wanted a ridiculous amount of money for them, and most were outside the US with high shipping costs to get it to me. I figured instead of spending $50-60 to get a used one, I'd see what I could do to 3D print one until I had time to find an original for a reasonable price.

I think it came out pretty good. I haven't ridden the bike with it installed yet (still working out other issues), but it seems fairly robust. Time will tell.

I've uploaded the model to Thingiverse. You can find it here:

Thanks to @Franz for helping me out with dimensions!

Here's what it looks like installed:
