I haven't printed these parts yet, but if anyone has already tried it, please let me know: whether we need to add or remove some parts, or whether we need to optimize the assembly details.

For the 250ml V4 version, you need one on the left and one on the right, or two on the left and two on the right; at the same time, you also need four H-type pins.

For the 250ml V8 version, you need 1 on the left, 2 on the left, 1 on the right, 2 on the right, and 8 H-type pins.

In addition, you also need 4 M8 bolts and nuts.

For the V8 330ml/12oz cooler, you need to use 8 H-shaped pins, with one on the left side of the V8, two on the left side, and one on the right side of the V8, and two on the right side.

Of course, you can make a 250ml V4 version, but the appearance of the finished product will be slightly less impressive.
