Rowing Machine Airflow Hood Adapter

Hey everyone!
I bought a fan flow diverting hood for my concept2, but noticed it kept slipping. This is primarily due to the fact that the new models of the concept2 rower have bumps that interrupt where the drawstrings lie. I've designed the attached solution for this problem, as this holds the drawstrings where they need to be. Print 2 of each of the pieces! The "nut" simply slides on to the side of the "bolts" to keep in place. It's more like a cotter pin.

Enjoy and happy rowing!

Here's a link to the diverter I purchased!
