BB ammo Thrust Bearing
Description
This Is A Printable Thrust Bearing That Uses 4.5 Mm Bb Gun Ammo As The Bearings. Just Print Two Of The Sides And Lay Bb'S In The Track And Sandwich Them Together. The Interior Dia. Is 10 Mm And 30 Mm Outer. Simple And Works Great. I Designed This Specifically To Go With My Windmill Design And It Obviously Helped Loads In Reducing Friction After Switching From The 608Zz Set-Up.
