E27 CEILING LAMP

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:
