Stackable, interlocking containers for small items

prusaprinters

<p>Here we have interlocking containers that can be arranged and stacked to organize parts, medicines, supplies, etc. &nbsp;For example, a tray 7 columns by 3 rows could organize AM, midday, and PM medicines for the week. &nbsp;Common uses include organizing fasteners, small parts, and sewing supplies.</p><p>Each stacked layer serves as the lid to the layer below. &nbsp;Thus, you only need to print lids for the top layer(s). &nbsp;Unlike drawer style organizers, the material redundancy of an outer shell with an inner drawer is eliminated, and you are not constrained to a single layer of storage. &nbsp; The rectangular stacks fit better on shelves and in drawers than hexagonal shapes.</p><p>The prototypes have only been printed with PETG at the 0.2mm, speed setting. &nbsp; Supports are not needed. &nbsp;Higher quality light-colored filaments that are not stringy are recommended. &nbsp;It takes some coordinated force to interlock multiple rows and there is some flexing of the walls during locking. &nbsp; PLA might not be able to handle the flexing. &nbsp;Small cuts in the dovetail geometry ease a pivoting, rotating move in one direction more than the other when interlocking groups of containers. &nbsp;</p><p>After printing, before assembly, file off any stringiness, and crisp up square edges as needed. &nbsp;Check the proper mating of all sides of a block one face at a time - each single face should be very easy to lock or unlock against another single face, and very easy to stack with another container. &nbsp;When multiple rows are joined, the unlock motions are opposed by the locked joints so the containers do not come apart except by using firm deliberate, properly directed force.</p><p>Two sizes of containers are provided - 45mmX45mm &nbsp;and 55mmX55mm outside dimensions with inside depths of 15mm and 25mm.&nbsp;</p>
