This remix addresses a few issues I had.
For one, the shower holder was WAY TOO SMALL. I don't know. if it may have been for some sort of non-US shower head, but I do know US shower head "holder" sizes are rather universal and my remix addresses this issue
Secondly, I essentially added a dowel to the "stand". This allows you to place the shower head into the hanging hook on the baby bath.
It's not the most secure, but it'll do in a pinch. Way better than trying to wrangle a moving baby and rinse them off at the same time. with only 2 hands. Hold both parts when adjusting
I used an M3 screw and didn't actually print or use the knob since the friction from the 2 parts seems to keep them together just fine.
Hope you can make use of this!
