Ultimate FU Bike Handlebar End caps

thingiverse

Photo is a custom version with initials, so ignore the BB, but the files included are for a basic hex-head and initials of Frank Underwood (FU). Print in something sort of flexible, like eSun PET-G. Orient so that the exposed part is up (for nicer finish) and use support. These are the best fit for carbon bars. If you have thinner aluminum bars, they may be a little loose - but you can just wrap a piece of tape around them before inserting them if needed.
