Small Parts Box with removable bins: improved

prusaprinters

<p>I quite liked the original model (https://www.printables.com/cs/model/263402-small-parts-box-with-removable-bins), but found several issues with it. These are my improvements and fixes:</p><ul><li>support for arbitrary sized box (the original failed for X &gt; 200 mm)</li><li>45° triangular slot for the lid (gets rid of the completely unsupported overhang)</li><li>configurable lid thickness, independent of the wall thickness</li><li>optional stiffening ribs for thin lids<ul><li>star pattern (should be more rigid with least amount of material)</li><li>dividers patttern: reflects the bin grid below, leaving flat spaces for labels</li></ul></li><li>more correct rounded corners radius (makes the walls constant thickness)</li><li>configurable optional fixed dividers (the original used fixed 2x3 pattern)</li><li>code cleanup<ul><li>removed several magic constants</li><li>wall thickness other than 3 fully supported</li><li>I think the slop calculations were wrong too? I got lost TBH</li></ul></li></ul>
