12mmx5mm Spider Coupler

This is a coupler meant for a 5mm shaft and a 12mm ball screw for a temporary fix on my printer.
I am using this coupler on my printer so I could use my 12mm ballscrews until I could find and purchase proper couplers. I would recommend having the top of the ball screw to be supported by a bearing.
The middle section shown in the picture as red was printed with Hatchbox TPU
UPDATE: Fixed alignment issue where one side of the spider did not fit properly
