IKEA Kabeldurchfuehrung

From the initial great design I just modified 56mm diameter part. As it was to deep for my desk plate I wanted to reduce the height that fits my needs. After struggling some time to edit the original .stl file I decided to redesign in Fusion 360.
I've added a partial thread(M56x2) to the base unit and created a fixation ring to be screwed on.
The sliding cover can be taken from the original thing.
