Please do send it to me. I will get this designed and print a prototype. I will make sure that you get your sample back after the design phase is completed.
I can provide a rectangular hole for the pull tab and also any other holes that would be present on ALL versions of plug ins. I believe that there are some holes that must be common to all versions. Possibly the 4 screws that hold the front panel to the upper and lower aluminum extrusions?
Looking forward to getting this part designed and printed.
