3rd party Widebore Tips for Flex

Hello Everyone,
we are getting a Flex soon and we are in the process of discovering possible use cases for the Flex.
One of them involves the usage of Widebore Tips. It seems that Eppendorf Tips are usable on the OT-2.
Does anyone know if there are fitting 3rd party tips out there which can be used with the flex?

Thanks in advance.
