Geberit auction

When you need to remove the Geberit bell from the cistern you need to unhook this part. Often, if the part is a few years old and is encrusted with limestone, the piece breaks.
Here I propose two types:
type 1, same as the original;
type 2, with a rod without edges, with greater resistance to breakage.
Feel free to use whatever you like!
I printed it in PLA, with supports.
