This is the IKEA 5 button pressure fit light switch cover. It is pressure fit so that you can still take it with you in the room or just to change the batteries in the IKEA switch when needed.
Supports were only used under the rectangle where the mains switch comes through but you can use more if your machine doesn't bridge large distances that well. Supports shown in photo.
On my Ender 5 with the stock hot end I found the best results were when the model was placed in a diagonal orientation on the bed to allow the part cooling fan the best chance of doing it's job.
Printed in a .2mm layer height.
Update: 2/18/24
Added v2 as I realized I forgot to fillet one of the edges to match the other side.
Right side when mounted is the one that was fixed.
The author marked this model as their own original creation.
