Worked as designed though a little tight to screw on for me, but had some stringing when I printed so probably my fault.

Hello, thanks a lot for your comment and for showing your nice make!
Yes, the E14 version has been designed to fit tight according to the fine thread of the E14 lamp holders. The E27 version has a less tight fit like the standard nuts delivered with the lamp holder.
I printed the nut with 0.2 mm layer height because that's usually well enough for home usage. However, if you want to use the nuts commercially I recommend a layer height of 0.12 mm for best results.
Best regards!
