AA Dummy Cell Battery Eliminator
A printed AA-sized dummy cell (14.2 mm diameter, 47 mm body, about 50.5 mm overall with an M3 socket-head cap screw as the + nub) that lets you power a wall clock, remote, toy or sensor from a 1.5–3 V supply instead of batteries. The two M3 terminal screws self-tap into 2.6 mm pilot holes, and the supply wires run in two 1.8 mm side grooves and tuck under the screw heads through end-face channels. The – end has a 7 mm × 1.6 mm counterbore so a low-head M3 screw sits almost flush.
Flagged: battery or DC power. Not for safety-critical use without independent engineering review.
EDC Flashlight Desk Dock With 14500 Wells
This 100 x 44 x 28 mm desk dock holds a pocket flashlight upright in a tapered cup that fits lights from 20 to 28 mm across. It has a push-out hole in the bottom of the cup. Four 15 mm wells hold spare 14500 or AA cells (14.5 x 50.5 mm) with about 24 mm standing proud so they are easy to grab, and a 16 x 34 mm tray takes keys or a pocket knife.
Flagged: battery or DC power. Not for safety-critical use without independent engineering review.
Tiered Remote Caddy With AA Wells
A three-tier stadium caddy for the desk or nightstand. It has three 24 mm-thick upright slots, 126 mm wide, stepped at 28, 40 and 52 mm with a 64 mm back wall, so every remote, meter or controller stays visible. A front row of six 15 mm wells holds spare AA cells (14.5 x 50.5 mm) standing up, ready for when a remote dies. The whole caddy is 130 x 100 x 64 mm and printed with thin walls.
Flagged: battery or DC power. Not for safety-critical use without independent engineering review.
Biped Electronics Battery Deck
This black 80 x 70 x 3 mm top deck is part of the 'SG90 Parallelogram-Leg Biped Walker' kit. It bolts onto the Biped Hip Servo Torso's heat-set posts with four M3 screws through 3.4 mm holes on a 64 x 52 mm rectangle. It carries a 4xAA battery holder, strapped on with a zip tie, and a controller on standoffs that screw into a 5 x 5 grid of 3.4 mm holes at 10 mm pitch. A 3 x 4 mm stiffening lip on the underside stops the deck warping or flexing and stays clear of the torso posts. A 30 x 8 mm pass-through carries the servo wires.
Flagged: battery or DC power. Not for safety-critical use without independent engineering review.
AA Screw Terminal Battery Holder
A four-cell AA holder (98 x 74 x 20 mm) with snap-in open-top channels on 18 mm pitch for 14.5 x 50.5 mm cells, so you can see and swap cells without a tool. Each cell end gets a contact window plus an M3 heat-set boss (4.0 mm bore) on top of the 9 mm end wall, so brass straps and ring-lug wires bolt down with M3 screws instead of being soldered to flimsy tabs; four corner ears take M3 clearance screws for chassis mounting.
