Variations For Fastening Things

A Remix of these awesome pieces from "Fastening things by emce". I wanted more attachment points to offer more options to tie to. Using these in a Side by Side Bed to tie down light cargo. Version 2.0 is an improved and stronger version of the previous design. I added some ribs and a heavier center column where the bolt goes through. I had one of the previous designs that failed at the bolt hole. I also used 100% fill in the area around the bolt hole and column.
