this is my own spacelamp, I printed the bulb by PETG (HDglass) and spiralize function set on my slicer. The base and the extension was printed by PLA, separated and then glued toghether. need 2 screw and bolt M4 x15mm for assembly the lamp holder and the extension. after print you need to cut the bulb bottom part.
tip: insert the electric cable before gluing the two parts
