Hex Nut Covers 5/16 in-18 thread

I didn't like the way the 5/16 hex nuts were visible so I made these to cover them. Both top and bottom screw in and work well. The depth of the hex head is 2mm so if you want your spinner to spin on a table top make your spinner cap thicker. I made the bolts and rods from openscad and NUT JOB https://www.thingiverse.com/thing:193647 Lots of testing and trial and error especially converting from metric to SAE here in USA. Hope this fits a need.
Let me know,
