[MENTION=44049]WheresWaldo[/MENTION] I'm not sure if this is the better place to contact you or on Shapeways. I'll post here then let you decide.

I have an older Felt DA tri bike with a 3.1 aero set post and was looking for a number plate holder. It looks like the Felt 1.1 number plate holder you have available on Shapeways may fit. What are the internal dimensions of your offering?

Felt does not make this 3.1 seat post anymore is why I am asking.

Thank you
Jon
