Battery holders for AA and AAA types

thingiverse

This is a battery holder with integrated wire connectors, available in AA and AAA versions. It's based on a design from Thingiverse (http://www.thingiverse.com/thing:9805). The holder conducts electricity to wires via M3 countersunk screws and embedded nuts. Several models exist for both AA and AAA batteries, identified by filenames starting with battery type and capacity. To print, use files AA_1_Battery_Holder.stl (single AA) or AAA_1_Battery_Holder.stl (single AAA). If using ABS plastic, print without a fan if possible. Clean wire holes with a 2mm drill bit, following this video technique: http://vimeo.com/14492980 (starting at 00:58). You'll need two M3 nuts, two M3 countersunk screws, and two wires per battery. Insert screws into holder holes from the battery side, then insert stripped wires into connector holes and nuts. Tighten gently to avoid cracking the plastic. Finally, attach the holder using two more M3 countersunk screws, as demonstrated in UseCase.jpg for a toy example.
