Flag system sailboat backstay

I wanted a way in which I could attach my flag to my backstay. There are numerous ways of doing so but I wanted a solution in which I could easily take down the flag. Its basicly two pulley with a 4mm flagline inbetween. I have adjusted the tension by moving the lower pulley down on the stay. 

Assemble with 2x M4x16 countersunk bolts. For those who want to be specific; DIN912. 

8mm version is tested, 6 and 10mm versions are untested, please let me know if they work! 

Disclaimer

My models are always tested on my own boat. We are currently cruising to the Caribbean and you can therefor assume that we load up the part properly. It is however your own responsibility to use these parts when heading out to sea. Use common sense and print spares if you are not able to print onboard. Especially on longer passages. 

Remix

Please remix however you like. If you are not able to design your own parts I do offer a modification service to those in need. A contribution for my effort is however expected. Send me a message on Noforeignland and I am sure we will figure something out.
