Ball Bearing with Airsoft BBs
Description
I Know There'S A Lot Of Ball Bearings (And Other Bearings) Out There On Thingiverse. This Isn'T Meant To Be A Crazy Invention, Just My Attempt At Creating A Bearing. I Thought It Would Be Fun To Design One, So I Did! It Prints In Two Pieces With No Supports. I Printed One In Abs And One In Pla And They Both Worked, But I'M Sure You Could Use Any Other Material Also. Once It Is Printed, Just Pop The Airsoft Bb'S Through The Hole That'S Meant For Them. In Total, You'Ll Need Twelve 6Mm Airsoft Bb'S. It Will Take A Bit Of Force To Get The Bb'S Through The Hole. That Is Intentional So That They Don'T Come Out. To Make It Spin Even Better, You Can Lubricate It. I Just Sprayed Some Wd-40 Into Mine And It Made A Huge Difference! The Clearance And Size Of The Pieces Was Idealized For My Printer, An Ender 3 Pro. I Had To Try A Few Different Times Before I Got A Fit That Was Loose Enough For The Balls To Spin But Tight Enough That It'S Not Wiggly. I Wouldn'T Be Surprised If It Printed Slightly Differently On Different Machines, So I Hope That It Works Well For You Also!
