Webbing adjuster buckles

Some crudely made adjuster buckles (ladders) in rare variations that allow for connecting 25mm tapes in in various orientations, for example if you want to add a chest strap to backpack. There's also a piece that allows connecting 25mm tape to a 40mm tape in a T-shape - useful for harnesses, and something I just couldn't find injection molded.
Some allow for sliding, some are made to bite into the webbing.

Print with as many walls as it'll allow, flat on the bed. I'd suggest something stronger than PLA - ideally Nylon or ABS, but PETG works just fine and so should PLA+. Fiber additives are overkill.
