Strain relief for RG58U coax - 3D print

I've been a bit slack with my dipoles here in the bush, the coax just hangs from the PL259. It's been fine until kangaroos catch the coax and rip the coax out. The repair isn't too hard but I thought I'd look for a way to relieve the strain on the connection and ended up with my own design for 3D printing.

It has a channel that the coax fits in to and two cable ties to grip it.


3mm cord lifts the coax slightly so that there's no weight on the PL259. 


I designed it in Tinkercad and you're free to grab it for printing for further modification here. It will be interesting to see what breaks when a Kangaroo goes through it next time.
