Summary

This is a DIY version of the Parantesi Flos Lamp.

You need:
An alluminum tube (about 11.2mm external diameter), and bend it and spray paint it
A IKEA GRAVACKA lamp holder (5€)
A nylon‑coated clothesline cable
2 M4 and 1 M5 for assembly, M5 require a self-locking nut because the lamp holder can rotate.
If needed, fit a large rubber gasket with a washer inside it to match the gasket’s hole to the M5 bolt and increase friction between the parts.
