SFu1610 nut reverse

Used to flip 180° a sfu1610 ballscrew nut within seconds, without loosing any balls and keeping them in place.
Printed in 0.6mm 0.3 layer height but anything not too fanciful should work.
Clean well before use (use a lighter to remove small plastic particle) and ajust the hole with a 10mm bit for a smooth operation.
Dont force on it its thin so not really strong. I used and recommand petg to avoid this.
