Spool Organizer - Closing, Stackable and Customizable

prusaprinters

<p>My version of a spool organizer features cleverly closing individual drawers (no extra parts), uses only threaded rods as additional hardware (m4 for drawers and m8 for spool stacking) and is customizable for any spool and size of drawers (currently set up for DAS FILAMENT spools). For stacking of multiple spools, fully 3D printed roller bearings are included.</p><p>&nbsp;</p><h3>Tips</h3><h5>Closing Mechanism&nbsp;</h5><p>The closing mechanism is achieved by a little flexible detent at the bottom of each drawer. This detent snaps in place on the adjacent drawer for closing. This keeps the drawers closed while rotating the spool and during transport.&nbsp;</p><p>For this closing feature to work, the adjacent drawer needs to be quite precisely mounted. For this reason a drilling jig is included (A and B side on the jig stands for top and bottom of spool). Heating up the closing detent with a lighter and bending it in place is enough to overcome assembly tolerances.</p><p>&nbsp;</p><h5>Assembly</h5><p>To mount the drawers, holes on both sides of the spool are drilled (A and B side of the jig). Use a 3.5mm drill and simply thread a threaded m4 rod in place. During mounting of the rod, press both spool flanges firmly together, to ensure that the two flanges are not spread apart. Use loctite or any glue to secure the threaded rod. You can also use any m4 bolt and nut of your liking or a 4mm pin.</p><p>The label frames are glued on the drawers with little superglue. make sure to leave the left side open to insert a piece of paper.</p><p>Stacking of multiple spools requires a M8 threaded rod, a complete 3d printed roller bearing in-between each spool and one on top and bottom of the spool stack. Glue the threaded rod in the bearing top cap, stack all spools and bearings and secure it with the glued threaded rod and cap.</p><p>The included bearing casings are fitted to DAS FILAMENT spools. If those do not fit, you can customize your own, or just cut off the orientation features with negative bodies in prusa slicer.</p><p>&nbsp;</p><figure class="image"><img src="https://media.printables.com/media/prints/241525/rich_content/5067fa34-2f06-45ef-9cdf-689ff76701cf/cut-away.png#%7B%22uuid%22%3A%227d96f5ec-7ecc-4328-9e76-a8bf199ddef4%22%2C%22w%22%3A1916%2C%22h%22%3A1000%7D"></figure><p>&nbsp;</p><h5>Customizable f3d file</h5><p>The spool dimensions are parameterized to fit any spool of your liking. The count of drawers&nbsp; per spool is parametrized as well. This changes the dimensions of the drawer. The parametrization and constraints are robust, but sometimes the drawer count value needs to be changed in 0.2 steps for fusion360 to be able to recalculate everything. The drilling jig is set up to incorporate one 90° drawer, 3 60° drawers and 2 45° drawers. I found this diversity in sizes is perfekt. Feel free to create any drawer size arrangement of your liking.</p><p><br>&nbsp;</p>
