Tether Hard Shell

This is an easily printed outer shell for tethers used on spaced walks. They interlock with one another to provide flexibility and adjustable length. These are put on tethers used for space walks to improve usefulness time and also strengthen them to prevent breaking. During walks the tethers can possibly rub against objects jutting out and rub an unseen tear into them. This is very likely to prevent a scenario like this from happening.
