Markup is set to $0.00 on all of these.
Here’s the link. Right now the badge itself has an ID of 33mm (to account for paint and VHB tape), which should work on many bikes that have a 31.8mm-ish OD head tube for a 1" steerer-ed fork.
(I can make other diameters if other folks are interested)
Just updated it to have a bunch of different colors and materials available.
I think @Mister_Uncle_Rudy 's is made from “polished bronze-silver steel”. Previously that was the only material other than pink plastic.
Let me know and I will update to any/all of the other materials shapeways offers if you want something else.
