Replacement rear housing for a motion sensor LED night light

This model is a replacement for the complete rear housing of a generic wireless LED night light with motion detection, sold by various retailers on AliExpress, Temu and similar marketplaces.

After the original night light was dropped, the internal mounting points holding the electronic board broke. Since this type of replacement part does not appear to be available separately, I remodelled the complete rear housing and printed it in PLA.

The replacement works like the original part:

• The original electronic board screws directly into the printed PLA using the original screws.

• The original upper housing clips onto the printed rear housing.

• The USB port remains accessible.

• The original magnetic adhesive pad can be reused.

I printed and tested the model on my own night light, and it works perfectly.

Compatibility

This night light is a generic product sold under several names and by many different retailers. Although your lamp may look identical, internal dimensions or mounting points may vary between versions.

Please compare your original part with the photos and model before printing.

Print settings

• Material: PLA

• Walls: 3

• Seam position: Rear

• Supports: Tree supports

• Supports are mainly required around the USB port and the recessed area underneath the magnetic adhesive pad.

• Print orientation: USB port positioned at the rear

The original screws are driven directly into the printed PLA. Tighten them carefully to avoid damaging the screw holes.

I’m sharing this model in the hope that it can help someone repair their lamp instead of throwing it away.
