Second modification
Appreciate the useful feedback Arjun!
Based on feedback and clarification, I created 2 configuration of the Al bend mount (the U-Bend and L-Bend)
...
I thickened the aluminium bend mounts to 1/8 inch = 0.125”. (Later I learned we can’t bend Al sheets thicker than 14 gauges = 0.064 inch so it won’t work, changing it back in the next iteration)
I thickened the base plate from 1/8 inch to 1/4 inch thinking that would give room to place counterbore. In this case, the entire base plate need to be re-made because it requires thicker material.
I placed the counterbore (M5) on the back side of the base plate.

Third Modification
Based on feedback, made changes on the previous modification. Again, Thank you Arjun, appreciate the feedback!!
...
Changes made:
Switched sheet metal back from 1/8 inch to 14 gauges.
Changed Holes on base plate from counterbored to countersunk. (the base plate is 1/4 inch thick).
Files are in the same location as previously made (the 08MAR2024 folder)
...
An exploration of where the bolt should be placed
Purpose: to see if M5 countersunk hole can fit on 14 gauge Aluminium sheet or 1/8 inch base plate.
14 gauge: does not fit, too thin, cannot be fully chamfered
...
1/8 inch plate: Yes it fits, can be fully chamfered
...
Just ideas: can try tapping the base plate and bolt the mount like figure below with or without a washer.
...
Or maybe this way, but I don’t know how this can be machined.
