7x7.3 Dragchain ends
extremely stingy economical and therefore like to recycle leftovers, I used a leftover piece of a 7×7.3 drag chain. Since the ends of the other part of the drag chain are installed elsewhere, I just scribbled and printed out 2 ends in 3D. Fits.
The parts can be downloaded from Dingsbums.
