I havent printed any of these yet but if someone does please tell me if it needs anything added or removed or if fittings needs to be better.

For the 250ml v4 you need left 1 and right 1 or left 2 and right 2, you also need 4 of the (h pin)

For the 250 ml v8 you need 1 left, 2 left, 1 right and 2 right and 8 (h pin)

and 4 m8 bolts and nuts.

The v8 330ml / 12 oz cooler uses 8 h pins and the (v8 left 1 and 2, v8 right 1 and 2)

you can make a v4 330ml but it wont look as good.
