<p>Replacement silicone sock for hot ends. Probably works for a lot of cheap 3D printers. You can check by measuring the block or printing part A and seeing if it fits your current silicone sock.</p><p>&nbsp;</p><p>Instructions.</p><p>Get some two part silicone putty. Any brand will probably do<i> (It's up to you to make sure what you pick is safe. Don't blame me if you find something that isn't)</i>. I think most will handle temperatures of up to 300C.</p><p>&nbsp;</p><p>Print the three STLs.</p><p>Take a ball about the size of a marble out of each parts of the putty and mix well.</p><p>Squash the ball of mixed putty into printed part B, skewering it on the alignment pin to make sure it surrounds it when pressed</p><p>Push printed part A into part B making sure the pin goes into the hole and the extension at the side lines up with the cutout.</p><p>Insert both parts into part C with the sticky out but going through the cutout and the open side of part B facing the open side of part C.</p><p>Push the sides together as hard as you can. There may be some leakage but that's fine.</p><p>Leave to set for 10 minutes.</p><p>Open the mold up and remove the sock. The alignment pin will break, don't waste time trying to save it.</p><p>Trim excess silicone and you're good to go.</p>
