A shim to fit a Shimano FD4500 onto a vintage Schwinn Varsity.
I inherited a crusty 1972 Schwinn Varsity from a hoarder neighbor and have been refurbishing it. The front derailleur was missing and a friend gifted me an old Shimano 4500 derailleur set to get it running again.
There's quite a difference in diameters between the seat tube OD and the derailleur clamp ID, so I came up with a shim for it.
This is what I came up with after a couple of iterations and tests.
I printed with 100% infill to prevent deforming or crushing.
