Interlocking Boxes

Voilà, a scalable box with dovetail joints for linking in a row! At its original size, the box measures 100mm on all axes, excluding protruding dovetails and ribs. Time and mass estimates are per box, at original size.Tolerance in the joints is provided by XY size compensation in your slicer rather than in the models themselves, so that it's unaffected by scaling. As long as boxes are printed at the same scale, whatever it may be, they'll mate together perfectly. A small test model is also provided for tolerance calibration.The ribs in this design keep the walls from bowing as flat walls otherwise would in a large vase-mode print. The photographs are of boxes scaled to 125% on their X and Y axes, printed with a 0.8mm nozzle.SetupXY size compensation (aka “horizontal expansion”): -0.1mm or so, whatever produces the best fit on your printerElephant-foot compensation: 0.2mmLayer height: 90% of nozzle size, for fast printingSolid top layers: 0Solid bottom layers: At least 2 layers, giving a total bottom thickness of at least 0.9mmInfill: 0%Infill-perimeter overlap: 35% – for a well-attached bottomExtrusion widths:External perimeters: 150% to 300% of nozzle size; ideally 1.2mmAll other extrusions: 225% to 300% of of nozzle size; ideally 1.8mmPerimeters:Quantity: Enough for walls 1.2mm thickSpiral vase mode, if only one perimeter – to eliminate all seams except in the bottom layersSeam position: Nearest – to minimize unsightly retraction flawsExternal perimeters first – to hide retraction flaws when possibleSupports: NoneVariantsDual-axis Interlocking Boxes – in case just one row of boxes won't doSimple Ribbed Box – a single box with no joints
