This is a replacement ceiling fan light globe that fits standard 3.5" base. My fan is a Hunter brand but it should fit any brand with the same fixture size. Printed mine in clear PETG for better temperature and outdoor durability.

I am using a LED bulb that generates less heat than an incandescent, so I have had no issues. However, I am not sure PETG would be temperature resistant enough for use with all bulb and fixture types, so select print material based on your setup and use at your own risk.

I printed without supports but did end up with some loose filament pieces inside. The use of supports will probably give a cleaner look when light shines through it.
