I had this amazing LED ribbon I had bought for a previous project that didn't work out so I used it as a light for my newly built Ikea kitchen. The LED ribbon can be cut every 10cm and needs a power supply. The sensor was bought from Amazon and it comes by 2 and is super cheap.

The 2 STL files attached are :

• the LED ribbon clips of which I printed 2 per meter and are to be screwed to the top of the baseboard with 3,5mm diameter screws;
• the sensor and attached box holder that's inserted onto the baseboard.

These things were printed on my Ender 3 with the standard 0.4mm nozzle in PLA with no support.
