I really like the design of the original leg holder by SoupCake.. It's awesome when we'ere bringing the chair when visiting friends and relatives.. However, I've had to print a lot of them, as they always mysteriously go missing.. So to avoid that, I completed one of the “arms” into a full loop, so that it'll stay on one of the legs..
I've printed them in PETG..
The author remixed this model.
Made one of the “arms” a full loop to stay attached to a leg.. Slightly expanded the loop to make it easier to attach..
