Configurable Remix Duncans Boxes

thingiverse

This is a remix and expansion of Duncan's battery boxes.I've had the worst luck when it comes to batteries leaking. Invariably, once one battery starts to leak, the corrosion triggers others to leak. Thus, my primary requirement for battery storage is that no battery should touch any other battery. His design achieves this while also being somewhat compact.This remix aims to consolidate as much as possible into a single parametric design while adding the ability to use cylindrical cuts and the standard half-disc coin battery cuts as well as magnetically latched lids. Open the "Configuration Table" and activate the desired battery type. Parameters not in the configuration table are available via the "Modify, Change Parameters" command.7-Oct-2023 Update:Reduced some of the excess magnet spacing so that the magnetic latch configurations are smaller/faster at least to some extent.Added a configuration option that creates a recess in the bottom box along the sides to make lifting it easier for those with less grip strength. The "Cut Grip" parameter has no impact on the lid.Uploaded the v14 Fusion360 fileUpdated the STL files that have magnetic latching to bring in the space savings. Added STL files for magnetic latching with the grip. Use the non-grip lid file, only the box file changes. The major differences include:Uses Fusion360 configurations feature - All battery types are in a single file (*.f3z)All sketch constants have been made parametricSome additional battery types includedLettering is omittedChoice of traditional rectangular cuts, cylindrical cuts, and half-disc coin battery cutsLids can be secured using the tab with pip design from Duncan's design or by gluing magnets into parametrically configured holesThe parameters default to 6x2 magnets (that actually measure 6x1.6) and with 0.2 mm slack for both diameter and heightMeasurements of object dimensions are intended to be exact. Those that prefer a tighter or looser fit can set the user parameters that include the word "slack". If your batteries actually deviate from the specified measurements, then it's appropriate to alter the dimensions directly, or create a new battery type.This is particularly useful for batteries that have a protection circuit included that increases the physical size beyond the specs (18650 batteries)The ability to add an additional wall thickness of material around the storage volume. Thus, a storage volume consisting of 2 cell columns in each row normally had only a single divider separating the two cells. If the "Outer Buffer" option is set to Yes, then there will be a total of 3 dividers - the standard center divider as well as one on the left and the right. The same applies to the "depth" dimension.One goal is that the design should be able to reproduce exactly the shapes that Duncan's design created. A perfect match probably isn't straightforward due to the fact that the slack included in Duncan's design varies by battery type. However, all other design aspects should be identical, when using the supplied parameters (except I think I use a larger divider thickness of 1.2 instead of 0.8). The extrusions and face offsets are copied directly from his design for the tabs, pips and such.Selecting the configuration options of cut type as rectangle, outer buffer as no, and latching as tab will produce a Duncan style box. Update: The grip configuration should be "no" unless the latching type is magnetic. It's the extra body volume that accommodates the magnets that is used for the grip recess. Otherwise, the cut may not leave enough material to prevent the print from coming apart.The included battery types are:AAAAACDNA23 (or 23A)PP3 (9 volt rectangular batteries)CR123AL18650 (L for Lithium-ion simply because some CAD programs have issues with configurations not starting with a letter)CR2016CR2025CR2032
