Ceiling Fan Shade adaptor

I recently bought some new plain glass shades for our ceiling fan but didn't realise until much later that they didn't have a grove at the top to fasten to light fitting on the fan.This is why i tried my hand at making a adaptor

WE ONLY USE LOW ENERGY LED bulbs so be wary of any HEAT THE BULB MAKES.

Its printed with PETg at a 20 % infill.
Hot end 215-220 C
Bed 70c
used a Prit power glue stick to help stick to bed

Ive linked the tinkercad files if you want to alter it to suit your own use
