Shower Pole Raiser

My shower curtain was too low in the bath, I didn't want to drill more holes into tiles, so I created this, it uses the existing shower brackets, and raises the shower pole up by 10cm.

It's designed for a 20mm shower pole, the small holes allow a screw to fasten them in place, there are two as I toyed with the idea of offsetting it by 45 degrees.
