Introduction
This 3D-printable spacer is designed to solve common issues with recessed or loose electrical outlets and switches. It fits between the device (outlet or switch) and the electrical box, ensuring a secure, flush installation.
Key features
- Universal fit for US and US-compatible electrical boxes
- Prevents sunken outlets and switches
- Improves device stability
- Easy to install
Perfect for both professional electricians and DIY enthusiasts, this spacer helps achieve a clean, professional-looking finish in electrical installations. Use it to:
- Level misaligned outlets or switches
- Provide additional support for devices
- Compensate for shallow electrical boxes
- Ensure a tight fit against wall surfaces
Compatible with standard US electrical boxes and devices, including single-gang and multi-gang configurations.
Usage
Simple
Download one of the pre-made STLs. They are 3.2mm (~ 1/8" thick). Print multiples and stack them as needed, or scale on the Z-axis with your slicer (every 100% scaling on the Z-axis will add 3.2mm (~1/8') to the thickness of the spacer.
Advanced (Parametric)
Open the model in OpenSCAD and adjust the following parameters as needed:
numberOfGangs specifies the number of slots in the electrical box (should select ≥ 1 to as many as your printer and/or wall box support!)
spacerThickness specifies the thickness of the spacer in millimeters
For example,
numberOfGangs = 3;
spacerThickness = 15;
will build a 15mm thick spacer for a 3-gang electrical box.
