Flexible Coupler Case

This case prevents the flexible coupler from blowing out or over extending. I typically level my X axis carriage by bottoming out the Z axis steppers on alignment bars and realized I was overextending and eventually trashed my flexible couplers.

These are designed to fit the 5mm to 8mm flexible couplers linked below. They allow plenty of lateral play while preventing the coupler from over extending. You will need to disassemble the Z rod assembly for install.
