Cover up your electrical cable junctions with this 85 × 85 × 34 mm friction-fit box.
 

3 parts, no fasteners between them — just press-fit assembly.
 

3 holes per side (8 mm) with optional plug covers for unused holes.

Why this design?
 - The box doesn't get in your way while wiring — install the base first, connect your wires, then cover.
 - Base mounts with 2–8 screws (2–3 mm).
 - Plug unused holes, snap on the middle section, top with the lid. Done.
 

Note: Not fire-resistant unless printed in appropriate materials. Electrical connections can overheat if poorly made or overloaded — use accordingly.
