Switchboard for IKEA LACK

thingiverse

This is my pretty easy to print switchboard designed for 19 mm LED switches fitting in the IKEA LACK. Instructions and Images in the Instructions section below. Enjoy! Print Settings Printer: ANET A8 Rafts: Doesn't Matter Supports: No Resolution: 0.2 Infill: 20 % How I Designed This FreeCAD Instructions What you need: The switches in the suitable voltages can be bought here. You need 2 x 12 V for the Raspberry and the LEDs and 1 x 230 V (depending on your line voltage, mine is 230 V). You can choose every color you want. A 12 V to 5 V Step-Down-Module to power the Raspberry Pi via GPIO. The converter can be bought here. Instructions how to power your Raspberry by using the GPIO pins can be found here. 1 x 20 mm drill for drilling the holes into the table. Approx. 1.5 qmm wires for the 12 V switches and 2.5 qmm wires for the power switch. And finally the printed switchboard.Instructions: 1. Solder the switches as depicted in the wiring diagram (only found one in german). Watch out for your current voltage and test it carefully before going on to step 2)! 2. Drill three holes at the correct positions so the board is fitting to them in the end. It is quite easy to get through the table due to its low thickness. 3. Drill or cut (or both like i did) a big hole with the length of the board to get access to your wires and to the switches which have to be mounted to the table by the nut (In the image the wires were not soldered completely). 4. If you've tested every switch if it's working properly you can already feed them through the board and fix them by tighting the nuts from behind as seen in the picture above. I recommend tagging each wire with its functionality not to get confused by this mass of wires and the dangerous amount of voltage. 5. The switchboard doesn't have to be glued to the table, if you attached the switches correct it should keep in position by itself. 6. Finally you can connect all wires to their correct pins. The PSU should look like this: Power input (L, N) of the PSU connected to the 7. Don't forget to convert the voltage coming out of the PI switch from 12 V to 5 V so you can power your Raspberry Pi.
