Double decker egg ramp (different size Mouldings)

I was only able to get the 30mm x 30mm mouldings from Bunnings (Hardware store in Australia):
https://www.bunnings.com.au/porta-30-x-30mm-3-0m-pine-moulding-fj-scotia_p8480377

I needed to make a different size bracket because the original creator used 28mm mouldings.

I have also attached the source files if anyone else wants to modify it to any size.
The source files are in Freecad format.

You need the rest of the files from the original creator:
