I own a cheap shower rail labeled with "CON:P".
One of the two rail holders broke.
Here is the replacement ;-)
You do not need to dismantle the tubes of the shower because the rail is clipped to the holder (different from the original).
I printed it with PET-G on an AM8.
The photos show the (still intact) upper original holder and the new holder designed and printed by me.

Update: the base of the rail holder also broke and I made a replacement:
