Moyu RS3M(And similar) Dual Adjustment Tension Tool + Keychain

Here is a quick mockup of a replacement or portable tension tool for the Moyu RS3M (GTS3) style system. I am new to cubing, and am still finding what I like best, so I quickly mocked this up to have a convenient keychain version so I can carry around and adjust as needed, without risking breaking or losing the clear blue one that is provided.

I have provided both a keychain version and a normal hollow version, as well as STEP files for both. I know its a very niche thing as most people adjust once and leave it be, but I figure if I wanted the ability, someone else might as well, so here it is! Thanks!
