In our last apartment, we had to saw our ikea ivar shelf in half to fit it in the storage space under the roof. Now in our new Apartment we have a storage space in the basement. So instead of buying new shelf legs by ikea. i just designed an adapter to screw the parts back together.
Used Screws 4mm x 20mm universal Wood Screw
The screws are not required but strongley recomended, to improve stability
I printed them with Bambu Lab PETG on the “Front-Side"
Fits on Ikea Ivar
