christmas lanterns

Açıklama

often our cr2032 batteries don't work anymore and we throw them away when there is still enough energy for days and days of lighting a led!!! This project is to finish using the energy left in these cr2032 batteries, it's very ecological, we don't throw away something that still works ... So a support to put a led in the Christmas tree and it will light up for days and days with a battery that we wanted to throw away..... There are 2 holes in the support to put a string and hang it in the tree .... but you can also fix with double face or with 2 screws this creation above the switches to guide you at night in the house ... A red led diode, it costs almost nothing, there is for cheap on your favorite online site (Ama.....) ... No other component, no assembly, no soldering, just a led and an old battery to light your tree ! (attention there is a direction of assembly: easy to find and no problem if you are wrong direction ... just reverse ...) on the edge: 2 holes on the edge to store the led when not in use nb: I add the freecad file for those who want to modify the project. nb: version 2 is with a little less play in the bracket.
