Since each L bracket is two part design you can mix and mach base ( currently 3 different length) with L bracket side ( currently 5 different length) to create your own custom L bracket.
If particular combination will be highly popular I will add them to my store as package.Please see drawing below for base and side specification.
Base 1
Base 2
Base 3
Side 1
Side 2
Side 3
Side 4
Side 5
I think we will use L bracket naming as base number and side number
So combination of base 3 and side 4 will be L bracket 34 - This particular L bracket will work with cameras with battery grip attached
