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.

Used HATCHBOX PETG since PETG seems to be slightly less brittle. My machines are all tuned for this Material, not set up for ABS. I am sure that you could print in PLA or ABS and get good parts.
