Ice Shot Glass Mold

thingiverse

I highly recommend checking out the print settings as well. I designed this for a friend's upcoming 21st birthday, but I thought I'd share the fun with everyone. I haven't had a chance to test this version yet, so I'll update it as soon as I can. UPDATE: It worked flawlessly. I want to stress how crucial it is to remove the layer lines (I sanded to 600 grit). It released from the mold very easily with only a couple minutes outside the freezer and a little warm water over the mold. To create your shot glass, put the two halves of the mold together and twist 90 degrees to keep the top part from floating out of place. Add water through the opening between the molds nearly to the top. Leave a little room for expansion (I haven't figured out exactly how much space yet). Freeze. Allow to sit out for a couple minutes after freezing. Twist the two halves of the mold and carefully remove your new shot glass. After printing, I highly recommend sanding the inside of the bottom mold and the outside of the top mold until there are no more layer lines. This should help it break free once frozen. Be patient with removing the glass from the mold. Sometimes it can take a while to break free. If it is especially stuck, run the outside of the mold under warm water or put some warm water in the cavity in the top part of the mold. Since Fusion and Cura don't agree on the axes and sometimes the dimensions, I've included pictures of the recommended printing orientation with dimensions. For me, this kept the inner surfaces of the mold as smooth as possible. I'm considering making a version with thinner walls, especially on the bottom part, to add flexibility and remove insulation to help the ice break free faster. If you're interested or have any other suggestions, please let me know in the comments below. I'd love to hear your feedback.
