Shower Bracket Replacement

My shower head bracket decided to give out and instead of buying a new shower head/bracket, I designed to design one that would fit over the existing one. I am not too sure how many other showers this may fit on, but if it has the similar bracket design it may work. This design uses 22mm M3 screws and M3 nuts as well. This is still a work in progress because some of the M3 nut holes are still a tad bit too small.

Last picture in the set is showing what the broken original bracket used to look like. As you can see, my first solution to the problem did not work as the 3m tape would not hold the shower head.

EDIT
In order to get this bracket to fit, you need to shave down the original piece that held the shower head. You can do this using a file and it should work fine.
