Parametric Box with flush hinges and magnetic closures

prusaprinters

<p>This is a basic hinged box with magnetic closures, fully parameterized in Fusion 360. It is designed with flush hinges for excellent stackability and arrangement.</p><p>It is intended to use 1.75mm filament as the hinge pin. The hinge pin path has tight tolerances but the insertion path is of a low friction design. Inserting the filament should be easy. Once fully inserted, the hinge pin swings into a blocked path so it won't work its way back out.</p><p>Fully parametric, including:</p><ul><li>Inside dimensions</li><li>Magnet sizes for the closure latching, including circular and rectangular variants</li><li>Automatic adjustment of latch wall thickness and magnet positioning for a given magnet size</li><li>Pretty much anything else if you're at least a little familiar with Fusion 360.</li></ul><p>This my first real attempt at a fully parametric model in Fusion &nbsp;360 and I welcome any comments and advice on how I built it from anyone with more experience. I'm always interested in novel or more efficient ways to construct!</p><h3>Customization:</h3><h4>Adjust Box inner dimensions and magnet size Parameters</h4><ol><li>Open the model in Fusion 360</li><li>Open the Parameters dialog box</li><li>Modify the <strong>inner_*</strong> parameters as desired (length, width, and height).</li><li>Modify the <strong>magnet_*</strong> parameters as desired<ul><li>If you have rectangular magnets adjust length, width, and height</li><li>If you have round magnets adjust diameter and height</li></ul></li></ol><h4>Activate Magnetic Closure Shape</h4><ul><li>In Design mode, be sure the magnet shape you want is <i>not</i> suppressed. Suppress the one you don't want.<ul><li>Rectangular magnets are controlled by the 8th item in the design history (named <i>Rectangular Magnet Extrusion</i>).</li><li>Circular magnets are controlled by the 9th item in the design history (named Circular<i> Magnet Extrusion</i>).</li></ul></li><li>Note that the depth of the magnet holes is automatically .2mm deeper than the magnet thickness by default so that the magnets don't bang together on closing.</li></ul><h4>Edit the text</h4><ul><li>In Design mode, edit the sketch named “Lid Text” to make any desired changes to the text.</li></ul><h4>Printing</h4><ul><li>Print the Box with its bottom on the build plate.</li><li>Print the lid with its top on the build plate.</li><li>No supports are needed.</li></ul><h4>Assembly</h4><ul><li>Put the Box and Lid together in preparation for the hinge pin.</li><li>Cut a hinge pin to length (just shy of the <strong>inner_length</strong> parameter value).</li><li>Insert the hinge pin into the hole on the right-hand end of the box as far as it will go. Use a bit of filament to push the hinge pin all the way in. I recommend PETG or any other durable filament fir for purpose.</li><li>Glue the magnets in place. Don't forget to verify the polarity of the magnets!</li></ul>
