Fix for wobbly leg on SÖDERHAMN couch

Required parts:

• IKEA Threaded Pins x 4: M8 60mm (Ikea part number 114509) or 75mm (Ikea part number 114509)
• M8 nut x 4: (Ikea part number 100712)

I have an Ikea SÖDERHAMN two seater couch that had legs that were a bit to shaky for my liking. 

After taking off the leg, I figured out it was the T-nut that was the cause. I tried to “stick” it with some epoxy putty, but that didnt work. 

So I tried to print a solution. 

I had a couple of spare threaded screws I had picked up from IKEA previously and decided to try out a few things. 

The old threaded pin on the leg is a 45mm long, I switched it out for 75mm long pin (60mm would also work). 

Decided that something needed to apply pressure to the wood, so I printed a washer that would go around the T-nut and apply the pressure from the nut to the wood. It works a treat!
