I changed out my console lid to one with storage but there is no organizer available for the jump seat type console so I made one on my printer.
I have the .stl files for these if anyone has access to a 3Dprinter.
Finally got it the way I want it so I can post a pic.

This came with the u bolts which i did not use. They were fine thread which I did not like. Used the stock ones as with the lower blocks I was on new threads and they were not stretched.
