Hello! The team that I am on is looking to build a swerve drive module in the off season as a proof of concept/learning experience. I have noticed a part that would be very helpful to us that I have seen in some photos online, but I can not find it anywhere. I have (crudely) circled in the attached photo.
Any help identifying/locating the part would be very much appreciated and would greatly help our off-season build.
Edit: To Clarify, we don't need the exact part (though it would be nice), but the name of this type of part and where to get it would be great as well.
It's not fair. it's not right, but stuff like this happens. If you don't get picked for finals tomorrow, get in those stands and cheer for those who did. Remember, this is FIRST. - wilsonmw04 [more]
