Make the Gantry sides drop to the inside of the ballscrew not the outside.? This will shorten the gantry width and reduce bearing plate width and cantilever making it stiffer.
It allows access from the outside to the ballnut for adjustment and greasing etc.

Make sure that you also think about how you are going to mount things like the ballscrew housings on, for example, the gantry sides.....(cough....don't ask me how I know!!) I'm using MGD16 ballnut housings which you can mount from the outside of the gantry endplates instead of some lower profile aluminium ones that I got from Aliexpress which I would have had to mount to the gantry side and then put the side on the gantry..............

gents thanks a lot, I'm going to change a bit to make it more rigid, I have an idea on my mind I'll work on, I just hope its good enough

I made a quick change to the gantry sides , reduced the width since its just going to be a waste with unnecessary cost and also hindering rigidity. gantry sides are now inside, will have to figure how to design the ballscrew holders with this design, but at least its not compromising (hopefully)

Try and keep the gantry sides all one piece like Jazzcnc first pic. Clive

What Profile are you using that those rails sit onto because the rails look nearly as wide as the profile which if 20mm or 30mm the profile it is far too weak.

That or things are very much out of scale which makes designing very difficult.!

Your change is weak and complicated so I wouldn't take that route.

How does this look?
