7x7.3 Dragchain ends

With my small [3D router](https://www.thingiverse.com/make:751414), the cables of the milling spindle are to be laid in a drag chain. Since I am ~~extremely stingy~~ economical and therefore like to recycle leftovers, I used a leftover piece of a [7×7.3 drag chain](https://amzn.to/2Gnvmfs). Since the ends of the other part of the drag chain are installed [elsewhere](https://amzn.to/2RP7jeV), I just scribbled and printed out 2 ends in 3D. Fits.
