create your own cast and oogoo to give your diy gadgets the shape you want

I think it\'s fair that every manufacturer is eager for a 3D printer.
You can replace the circuit board connector, repair the glasses, make the ski handle, make the whole machine with printed plastic parts
Even a 3D printer.
But if you don\'t have a 3D printer on hand, you can always turn to Su Ru.
Sugru is a dry semi-rigid silicone rubber putty with super strength.
While Sugru is cheaper than a 3D printer, it has a small package and limited color.
We need something cheap and customizable.
So, today we made some DIY silicone rubber with corn starch and silicone caulking agent, aka Oogoo.
What is the first step in the material?
The possibilities of Oogoo are endless.
Packaging mobile phone, making circuit board bumper, making flying disc, casting robot parts
The world is your oyster.
No matter what you end up doing, you need a model of the object you want to create.
You can make a model of the original object with the plaster of Paris.
I decided to make a small project box for my first Oogoo casting.
I put one tin in another tin to create space for the mold.
I tape the sides of the inner tank to hang it up and leave room for Oogoo to flow below.
Step 2 what you need to do to mix is add some corn starch to the silicone.
Make sure you wear gloves because the silicone is inherently evil, and it will annoy you for a few days if you get it on your hand.
Some people complain about a slight allergic reaction if they don\'t wear gloves.
Wear goggles and safety masks at this time.
There is no real danger, but the smoke from the mixture is not pleasant.
I used a Dixie cup.
If you want to fill in multiple molds, you will want a larger container. A one-to-
After a few hours, the ratio of starch to caulk will dry.
Less starch means a longer drying time.
I found that-to-
A scale is too thick to flow into the mold as I thought.
I ended up with a volume ratio of 2 parts of silica gel to 1 part of starch.
It\'s hard to stir this mixture, but stick to it! It will blend!
Adding linen oil paint now will bring some vitality to your Oogoo and will also help you see when to reach a uniform mix.
Step 3 Pour the mixture into the mold and set it.
Wait at least two hours before checking your Oogoo.
Remove the mold from Oogoo by separating the plaster or metal mold.
If your object has a flat side like tin, you can also pry open Oogoo with a butter knife.
Oogoo is very flexible and will not be destroyed and can pop up easily.
It should have a shiny white finish.
Oogoo can easily fall off plastic and metal.
Step 4 profit. now you\'re limited by your mold. making skills.
Play around in different proportions to see what works best for your project.
Remember, you can drop thick objects like a robot\'s limbs, or you can throw thin mats and disks.
My first Oogoo attempt ended in failure.
I used too much starch and the mixture set too fast to form a full mold.
Despite the failure, the bottom of Oogoo\'s work came out shiny and flat!
Now I have an Altoids tin mold made by Oogoo!
I want to embed some Altoids.
Size circuit in Oogoo mold.
Oogoo is basically a removable shockproof circuit board.
My second attempt at casting the Altoids lid was very successful!
The tin and body molds work perfectly with each other and it is easy to apply this technology to the manufacture of valves, servo brackets, watches and underwater electronic enclosures.
Oogoo is definitely the new board choice for all my portable projects.
It is very cheap, waterproof, shockproof and customizable!
