This cap was designed to suit my 2014 Trek Fuel Ex 5 to cover the direct mount derailleur hanger.
This will likely fit many other models however, has only been tested on the '14 Trek FE5.
Test printed in PLA, would recommend other material for long term use.
215/65
PanTech black PLA
Printed without supports (depending on print orientation).
The author marked this model as their own original creation.
