Ikea Koppla 6-way Outlet Splitter Holder

The Ikea Koppla is a 6-way Outlet Splitter (North American). It turns a 2-outlet/duplex receptacle into 6 outlets.

However, there is no easy method of securing the Koppla to the wall. Once plugged into the receptacle, only the friction of the metal prongs are holding it in place. If you try and unplug a power cord from the Koppla, it'll often detach from the wall receptacle. 

This adapter will allow you to secure it via the receptacle's wall plate screws. This is designed around the Leviton Decora line of receptacles. But using the parameters, you should be able to adjust it to any common receptacle.

If you open the .f3d Fusion 360 file, there will be two parameters you can just (Design mode > Modify dropdown > Change Parameters), assuming you have the Koppla plugged into the receptacle:

• top_length - this is the distance (in mm) from the top edge of the Koppla to the center of the top screw that holds the receptacle's wall plate, default 9.45mm
• bottom_length - this is the distance (in mm) from the bottom edge of the Koppla to the center of the bottom screw that holds the receptacle's wall plate, default 5mm

Print in PLA or PETG, 0.2mm layer height. I managed to print it on a Mk3S+ without any supports. Further discussion here.

To install once printed:

1. Remove any power cords connected to the Koppla and also remove the Koppla from the receptacle.
2. Unscrew the two screws (top and bottom) holding the wall plate around the receptacle, but do not remove the wall plate.
3. Plug the Koppla back in. Put the 3D printer holder on top/around the Koppla, lining up the screw holes.
4. Secure it all using the two previously removed screws. The screws should be go through the 3D printed part, the wall plate, and into the metal bracket of the receptacle. 
5. If having issues, try only screwing the top screw a few turns only (until the thread catches), and while pushing on the Koppla against the wall, screw the bottom screw in. Then secure the top screw.
