Balancier Couplings (Kupzinger)

[65 1057]

I just found a replacement coupler for the standard LGB bottle opener couplers.
It seems to need very few modifications...
Since I never handled 3D printed parts so far on my layout - has anyone experience with these Balancier Couplings?

I like the idea of reliable couplings which significantly improve the look of our rolling stock...

As of 01:30 he explains his idea with the help of a prototype:

An interesting concept, but for me to equip all my stock with these couplings would be a huge task in terms of time and expense.

Although the LGB 'bottle opener' ( I like that!) couplings are unsightly, I'll be sticking with them....

Like Gizzy there would be a lot of work for me, I have hooks both ends of all my stock with LGB bottle openers, so uncoupling never a problem. I have no hooks on locomotives and drop the bottle opener 20-30 thou. I do like these though and perhaps at an earlier stage of my lines development may have considered them, they are perfect for my Harz setup. BUT I would be concerned of decoupling with the magnets on a longish train. My line has trains up to an additional 1 1/2 times the length of his demo on R4 curves up 1:40 grades, hence my concerns.
