For broken wall mount/base replacement on the Flamma lamp of IKEA.
A great lamp by Carl Öjerstam, made in Italy
Its not hollow as its not necessary.
Print like 50% PETG and use organic supports, just for the protuding part.
The grey mounts on pic are original, the black one is my make.
The left lamp has a broken seat, the two on the right are ok.
The author marked this model as their own original creation.
