18650 Battery Top Deck
Part of the 'NEMA17 Self-Balancing Robot Frame' kit (print ×1): the 120 × 80 × 4 mm top deck, which bolts to the stack columns with four M3x10 screws through 3.4 mm holes at (±44, ±34). A tray with 2 mm walls rises 14 mm above the deck and holds a 3S 18650 pack in a 70 × 58 mm space. Four 20 × 3 mm slots take two 20 mm hook-and-loop straps. A 12 × 8 mm notch in the end wall and a 20 × 8 mm floor slot route the battery leads down to the electronics deck.
Flagged: battery or DC power. Not for safety-critical use without independent engineering review.
