Does anyone make a better mount?

I have the tools to install additional water bottle bolt threads however the shape of this frame is an upside down v on top. I thought of getting someone to 3D print something to go under to fill the gaps. Does anyone out there make a better mount for this area? It’s a bafang special from aliexpress. Seems like a common piece but they are all cheap looking. Has anyone made nice ones to sell aftermarket? Or should I just throw in two more bolts up above in the other slots?

Your instinct is correct, you should design and 3d print something that fills the gaps so the battery mount can sit perfectly flat and resist twisting around your frame. I posted a pic of my setup.
Underneath the 3d printed plastic is a flat steel bar that runs the length of the battery mount. Steel hose clamps wrap around my bike frame and the steel bar, locking both to the frame and sandwiching the plastic in the middle. The steel bar has several drilled+tapped holes (sort of like the Triple Bob thing posted below) in it and that is what the battery mount is actually screwed in to.
This thing has been rock solid for \~5 years now, my battery has zero flexibility or movement when its locked in, and I have given it plenty of opportunity to do so in a bunch of crashes. The battery mount is basically a part of the frame at this point.

I have similar battery and the way it rattles when locked into the mount isn't really comforting so I use a velco strap around frame and the battery which makes it quieter and a bit more secure.
