I have included a lamp_top_template so you can add your own shapes, patterns, etc., and you can customize the lamp_bottom_template to add your own light source. I have included a photo of the bulb holder and bulb I used for the included lamp_bottom. I used a B22 golf ball led bulb, and my bulb holder thread diameter is 27mm. You can also use a normal-sized LED bulb.  

The filament I used was a little transparent, so I upped the wall line count and top and bottom layers because I didn't want the infill pattern to shine through. Both print without supports.  

Print settings for lamp_top_butterflies and lamp_bottom

Wall Line Count: 9 Top/Bottom Layers: 9 Infill: 15%  

Thank you for supporting my design. I really appreciate it.
