I spent a lot of time working on this model and I'm really happy with how it turned out. The print profile I've added should be good but there. are some internal overhangs you may want to watch out for. The screws were designed to be the tightest tolerance possible so they will be difficult to get on, I recommend using a towel and pliers to get it on all the way. DO NOT FILL THE CONTAINER WITH WATER OR IT WILL EXPAND AND BREAK THE PLASTIC

Antifreeze Gel-

2 grams- sodium poly-acrylate

1 ⅓ cups- water

⅔ cups- propylene glycol 

4 or 5 drops of blue food dye

Make sure to add the sodium poly-acrylate to the container only and not to the solution otherwise it will be too thick to pour in, also be sure its well mixed and the gel has had time to form before freezing
