Spacer with rotated holes for shower column

I have created this piece to fulfill my needs on a shower column from Leroy Merlin, precisely the item Column without battery Trend Kuchinox, purchased in Poland. The outer diameter of the item support is 40mm and it is smaller than the previous one I had to replace. This allowed me to avoid drilling on the tiles and still hang the column to the wall. The piece is very simple, as I intend to find a cover for it or at least try it.

 I used the original hardware of the item to hang this part to the wall, and I used M3x10mm screws to hold the column piece to the part. To make it stronger, I used brass inserts M3x5x5mm. Measurements in the photos.
