This is a simple design for a bathroom radiator hook. The pipes in my radiator are 23mm in diameter, check if this is true for you or resize the model to fit your needs.

This print doesn't require supports.

Also be aware of the softening point of you print material if you are using the towel warmer. In my case I don't need to worry about that since the radiator is not being used. In any case I don't recommend the usage of the hook in a warm radiator. Do it at your own risk.

I used PETG for a stronger print.

I hope you enjoy this model and let me know if you had issues or if it works for you. I would appreciate to see your makes also, that really makes my day.
