Super Simple Silicone Sock Mold for E3D v5 Clones
I designed this thing because most of the silicone molds here at Thingiverse are way to complicated in printing or molding to be honest.
This mold is made up of only three parts and requires nothing but a good hour of printing time and an rubber band for securing. Further fixation shouldn't be neccessary because the parts fit together firmly.
Please don't ask about the correct silicone, there's plenty of information available online and I don't want to be responsible for setting your home on fire. Make sure the silicone can handle the highest temperature of all materials you're printing. I used a special silicone that can handle temperatures up to 450 °C.
Print all three parts with 0.1 mm (recomended) or 0.2 mm layer height. Make sure to use enough bottom/top layers - it must be water-tight!
The two outer parts of the mold need a little support at where the openings are raising like a one-stepped stair.
1. Assembling the printed parts
Wait for the parts to be cooled down and press fit the core into on half of the mold. Press fit each halfs together and secure with a rubber band.
2. Preparing the silicone
Now it's time to prepare your silicone: Most of them must be mixed up from two components. Read the instructions precisely and don't waste it: 2 g (grams) of silicone is more than enough for one sock.
3. Filling the mold
Place the mold with openings at the top right in front of you and use a toothpick for picking up small amounts of silicone.
Let silicone evenly drip into each of the openings. Wait a few seconds before dripping in some more. The silicone will slowly flow into the inner of the mold and you will notice it will stop once the mold is filled.
Make sure the mold is filled up right to the top of the mold.
4. Getting rid of air bubbles
To get rid of air inside the mold once the mold is filled, put the mold in one hand and slap it brief agains the palm of your other hand. Eventually you will see air bubbles rising and the silicone is no more level with the mold. Use the toothpick again to drip some more silicone into the corresponding opening.
5. Letting the silicone cure
Read the instructions of your silicone components and wait for the declared time (mostly 2-3 hours). Have some patience and don't open the mold before time's up!
6. Opening the mold
Remove the rubber band and try to carefully remove one half of the mold. It can be helpful to use a precision knife to free the silicone from the openings at the top. Once the first half of the mold is removed, repeat the step above.
Don't rush this or you will likely destroy the silicone sock!
7. Cleaning up
Simply use a precision knife or nail scissors to clean up your sock and pull the sock over the heater block.
