Spindle for 5lb spool

This is a spindle for the Home Depot cord reel. With some slight modification to the reel frame, it will hold a 5lb spool such as the one sold by UltiMachine.
This spindle has very low friction. I uploaded the original design and a version 2 design of the bottom piece that I thought would use less plastic. I checked the gcode generated for version 2 and it looks like it uses more plastic then version 1 using 25% fill. I have not yet printed the version 2 design. So let me know how it works if you decide to print it.
