This project may have gone too far.
Following my little assembly to integrate the GNSS antenna on top of my QMX+, I thought I'd go a step further and create a sort of case for the threaded rods that connect the front and rear. Then I thought it would be desirable to put additional supports along the length of the case.
Finally, I arrived at what's pictured. The case is almost invisible under the layers of PLA :-)
