M40x2,5 Fixation nut for E27 lamp finger shape

A practical M40x2.5 fixation nut designed for E27 lamp holders. It makes mounting lamp shades with E27 bulbs easy and secure, ensuring a stable and precise fit.
The shape is finger-friendly, allowing quick tightening and loosening without tools.

Optimized for fast and accurate 3D printing, it fits most standard E27 lamp holders and shades.

If you are printing on your own setup, ensure that you have X-Y Hole compensation active. For me 0.25 works and gives nice tight fit.
