<p>I started printing nylon and have found the tedium of needing to oven-dry it too much to take. I've also had occasional sputtering from PETG that had gotten a bit moist, so decided to resolve.</p> <p>These are support backets for supporting 1/2" EMT pipe which is commonly available in the USA for pennies per foot. They can be used for any purpose but were intended to be used for creating dry-box like in this video:</p> <p> <figure class="media"> <oembed url="https://www.youtube.com/watch?v=OY5n9q-wS7k"></oembed> </figure> </p> <p>Enjoy !</p> <p>-=dave</p> <h3>Print instructions</h3><h3>Category: 3D Printer Accessories Summary</h3> <p>I started printing nylon and have found the tedium of needing to oven-dry it too much to take.

It's not critical but you want to allow enough space underneath for the desiccant but also not have the spool hit the box top. Adjust accordingly based on your spools.</p> <p>Cut 4x sticks of the 1/2" EMT to 313mm. A tubing cutter makes it much easier than using a hacksaw but whatever works: <a href="https://www.homedepot.com/p/Husky-Quick-Release-1-1-8-in-Tube-Cutter-80-772-111/204258904">https://www.homedepot.com/p/Husky-Quick-Release-1-1-8-in-Tube-Cutter-80-772-111/204258904</a></p> <p>Use one of the containers to mix all the desiccant together. This saves cost buy reducing the amount of more expensive indicating desiccant and the chemical it uses (more important if you are using the "blue" cobalt indicating desiccant, which is ever so slightly toxic). You can of course use all indicating desiccant if you want: it's your cash :). If you want to double this recipe to 8x boxes, you can probably just add 10lbs more non-indicating because there is still plenty indicating desiccant to show if it gets "wet" and the amount here can probably be stretched to 6 containers or more.</p> <p>Crack open a beer because you're done.</p> </li> </ul>
