For a boat installation I created a custom electrical box to have one central place for all wiring, relays, smart LED controllers as well as switches.

This is a work in progress so expect updates soon.

The box has a magnetic lid and a custom Wago rail system to mount different configurations (3x or 5x 221 Series) in a slight angle to preserve space. It als features an additional lower modular part fitted with M3 nuts to mount custom hardware like controllers, relays, etc …

On each side (L/R) there are 4x M16 mounting holes with custom caps for sealing. On the bottom are 3x M12 mounting holes.

The rear has 4x M5 Threads for mounting.

Printed Parts:

• 1x Box Base
• 1x Box Lid
• 2x Box Lid Handle
• 8x M16 Caps (Screw & NutCaps) - optional
• 3x M12 Caps (Screw & NutCaps) - optional
• 6x Wago Clamp Holder

Sourced Parts:

• 13x M3 Melting Nuts
• 4x M2 Melt-In-Nuts
• 4x M5 Melt-In-Nuts
• 4x M5x10 Hex Screw
• 4x M3x6 Flat Head Screw
• 4x M2x6 Hex Screw
• 8x 12x2.5 Magnets (https://de.aliexpress.com/item/1005001627825816.html?spm=a2g0o.order_detail.0.0.291d6368zpX5w3&gatewayAdapt=glo2deu)
