This little guy is cool enough to Halloween up the kitchen, tho.
Step 1: Download a Model From the 123D Gallery
When I saw Mr. Fish by Chuck Norris, I knew he was the one..! I used an Objet Connex at Autodesk. This guy is pretty simple, so a Makerbot should work totally fine.
Step 2: Set Up for Your Casting
Small plastic aquarium (you can use glass, but it's heavier)
Decorations for the aquarium - gravel, plant
Encapso from Smooth-On
Measuring cups and larger mixing container
You can set up your fishbowl now - I wanted black gravel and a single, cute little plant for my fish.
Step 3: Cast - Away
Encapso is a 1:1 mixture, so I just filled two paper cups to the top and combined them in a larger beaker - gently stir for a few minutes and pour into the fishbowl slowly to minimize bubbles. Repeat until you get up to the fish's level.
Don't worry about bubbles too much, unless it's under the fish itself. They seem to work themselves out before the material cures.
For this one, I experimented with dangling the fish by thread in the Encapso so that it wouldn't lay down or sink. If I had been a bit more prepared and cared to, I would have watched Martha do it and followed her lead.
Step 4: Remove Support and Fill In
In the future, I'd use the string and coffee stir support here, but with only the bottom of the fish in the Encapso. That way it will cure and hold the fish in place. Then you could fill the rest of the aquarium up with material and not get the little bubbles from the thread.
AND, for the next one, I think I'll put a little hole in the back and seal in some LED strip for lighting.
