<p>After printing <a href="https://www.printables.com/social/76750-duncanamps">Duncan's</a> <a href="https://www.printables.com/model/38533-duncans-battery-box-collection-aa-aaa-pp3-23a-now-"><strong>AA Battery Box</strong></a>, I wanted a AAA Battery Box with the same external dimensions. Box holds 40 AAA Batteries.</p><p>Included Fusion360 (.f3d) and .step files in addition to the STLs in case someone wants to create other battery layouts while maintaining consistent external dimensions.</p><p>This is a remodel in Fusion360 from scratch by me, using the printed AA Box for dimensions; <strong>it is not identical to Duncan's</strong>. For instance, my lid has more play on his box than mine, so dimensions are certainly <i><strong>not identical</strong></i>.</p><p><i>Note 0: I have not modeled the battery size letters into the lids, as this is trivial to do if desired in Fusion360 using the .f3d file or TinkerCAD using the STL files. I personally used matte black vinyl to label the lids as well as provide a QR code to a google sheet used for logging NiMH usage.</i></p><p><i>Note 1: To keep AAA batteries from moving excessively, the BatteryBoxLid_AAA model is 5.9mm thicker internally to maintain same clearance as AA BatteryBox Lid (~1.55mm); I have cut 2mm black foam common in packaging and glued it to the interior, removing vertical movement and associated noise. This increase in thickness resulted in only +0.93g ( ~0.03USD ) additional PETG vs the AA Lid, using the print settings below.</i></p><p>Printed in PETG with 0.4mm Nozzle, 0.2mm Layer Height, 10% Grid Infill, and 3 perimeters.&nbsp;</p><p><i>‘BatteryBox_AAA’</i> printed in 7hrs 11m (on MK3S)</p><p><i>‘BatteryBoxLid_AAA’</i> printed in 3hrs 31m (on MK3S)</p>
