Cord Tensioner (Q41958)

This device allows you to string an elastic cord through the hole and tighten it by 90 degree rotations. I'm still waiting on my ToM to ship, so I don't know how well this will print or whether or not the clearances will work. I placed the holes for #8 ANSI bolts (I think), but they shouldn't be hard to enlarge. edit: Rotated the models so they sat flat on the right axis, replicator g was surprisingly good at this.
