Note that I printed this on an Artillery Sidewinder X1 but pinshape does not allow me to select that printer and at the same time it forces me to enter a printer name in order to submit this print, so I had to enter a random printer. Ridiculous! My thoughts on the design of the model: From a printing perspective, this is well designed, However, I ended up not using it because when you try to use it, you understand why most such buckles are designed to open by pressing on both sides: the single button design in rather uncomfortable to open because you need to both press and either push or pull from the other side. This works, but it is far from the comfort that you get from pressing the two sides and the buckle just opens more or less by itself. The advantage of the one-button design is, of course, that it is much sturdier.
