A simple table leg brace (or shelf support?). Its not fancy, but it does the trick and its super easy to print with just about any material. And if you need a different size I've included the original Free CAD file so go wild.

The story behind this part is that when I got my printer, the only spare table I had at the time with an Ikea LACK night stand - which is an incredibly poor choice for something like the Bambu Lab H2D. Didn't help that its sitting on carpet. And while I was shopping the jungle website for a more suitable table, I came to the realization that I now have a 3D printer - why not first try to improve what I have for a fraction of the cost as a new table. 

The brace itself is solid - very rigid and on any other table it would work wonders… but this is a LACK night stand and behind the wood grain façade is sparce filled cardboard. Getting the screws to bite on anything is delicate work. For now it holds, and the nightstand shakes noticeably less so I call this a partial success. 

I have plans for some other modifications to this table to further improve stability, and I'll share as well once I get around to them. Who knows, maybe by the time I've spent as much on filament as I would on a proper table I'll finally remove all the shake out of this thing.
