horizontal filament spool drybox

prusaprinters

<p>This is a simple filament drybox that holds a single spool horizontally. The only modification that need to do to a sealed container is to drill a 10mm diameter hole for installing pneumatic connector.&nbsp;</p><p>Assembly after print took only about 5min.&nbsp;</p><h3>Assembly instruction video:&nbsp;</h3><figure class="media"><oembed url="https://youtu.be/Yl8VJgbbo-A"></oembed></figure><h3>Off-the-shelf parts you need:</h3><figure class="table"><table><tbody><tr><td>Part name</td><td>number</td></tr><tr><td>Sealed container(about 5.5L or more)*</td><td>1</td></tr><tr><td>Desiccant</td><td>as many as you like</td></tr><tr><td>Hygrometer</td><td>(optional)</td></tr><tr><td>608zz bearing(ID 8mm,OD 22mm, H 7mm)</td><td>1</td></tr><tr><td>M8 bolt with 20~25mm length</td><td>1</td></tr><tr><td>M8 nut</td><td>1</td></tr><tr><td>M8 washer</td><td>1</td></tr><tr><td>PC4-M10 pneumatic connector</td><td>1</td></tr><tr><td>M10 washer</td><td>1</td></tr><tr><td>M10 nut</td><td>1</td></tr><tr><td>PTFE tube(ID 2mm, OD 4mm)</td><td>distance from your drybox to printer</td></tr></tbody></table></figure><h3>Tools you need:</h3><figure class="table"><table><tbody><tr><td>Tool name</td><td>number</td></tr><tr><td>Drill</td><td>1</td></tr><tr><td>10mm drill bit</td><td>1</td></tr><tr><td>Adjustable wrench</td><td>2</td></tr></tbody></table></figure><p>*The sealed container I used is ASVEL KBOX F-30 5.6L with internal dimension around 285*192*100mm.</p><h3>Note:</h3><ul><li>For spool holder disk, choose the one that fits your M8 bolt. If using a hexagonal head bolt, prefer using “spool holder disk for hexagonal cap M8 bolt”.</li><li>In order to make this design fits to different sizes of container, you may modify the length of spacers.</li><li>To accomodate different spool hole sizes, insert the tapered pin to different holes in spool holder disk.</li><li>All 3d printed parts need no support structure if oriented properly. And all of them are hollowed out to reduce filament usage.</li></ul><h3>The reason I chose to design horizontal drybox instead of more common vertical drybox:</h3><ul><li>Most sealed containers about the size of a spool are shallow in depth. Which only allows spool to be placed horizontally.</li><li>Converting a container that is designed to be used horizontally into vertical, takes effort modifying the side of the container, and sometimes need drilling more holes, which may introduce more moisture leakage.</li><li>There are many horizontal spool holders that are usable. Which means my design isn't too weird.</li><li>Horizontal containers are stackable, whick ends up in smaller footprint. If not stacking too many of them(about 3 or 4), there isn't much difference between picking the top one and picking the bottom one.</li></ul>
