LAMP with adapterring for standard E27 thread.

Print with support “trees”, uncheck “only critical support”

Gently work the E27 adapter back and forth to the lampthread to make a perfect clearance before assembly.

If if you have your own lampdesign, simply use M75x4 thread and scale the model +4% ( *1,04) in X and Y to fit the adapter.

If you want to make your own adapter, the E27 thread is M40x2,5 with a +3% scale (*1,03). Same scale for outer M75x4 thread.

The small E27-nut seen in pictures is optional, but simplifyes assembly, se my other upload:
