battery spacer 3d model

Design a 3D printable dummy battery insert (mockup spacer) that replaces two AAA batteries in a remote control battery compartment. The part must accurately replicate the physical dimensions and layout of two AAA batteries placed side-by-side in parallel (each 10.5 mm diameter, 44.5 mm length), so it fits perfectly in the battery slots. Requirements: Exact 2×AAA battery external shape simulation (no separate battery holders) Solid single-piece block or two fused cylinder-like shapes Must match real AAA battery spacing and alignment in a remote control No electrical functionality required (pure mechanical spacer) Lightweight but rigid structure for FDM 3D printing Smooth edges for easy insertion and removal Must prevent movement or rattling inside the compartment Optional: small grip tab for easy removal The final model should act as a perfect physical replacement for two AAA batteries in a remote control.
