Printable LM8UU bushing for SmartRap

I needed to make the outer diameter smaller, and inner diameter bigger to fit this into the Smartrap parts and over a 5/16 aluminum tube (instead of M8 rod).

For some reason Cura will not print the first layer for this part. So I used tinkercad to put 4 of them on a .2mm thin platform that you can peel away.

Please print using .2mm layer height.
