My aero bars end caps got roughed up a bit from an accident so designed this as a replacement. I will post pictures soon.
*added the skp files so its easier for others to edit/modify.
design notes:
v5: I had to take a knife and cut down the top 2 rings a little bit to make it fit better. the tip was also very pointy to where it seemed like a hazard. so had to trim that down with a knife as well.
v6: shrank rings slightly, rounded the tip.added an internal structure to hold top ring on better.
v7: made it so it could print without supports, forgot to shrink rings though so they still may need cut down with a knife.
