Lamp Shade Adapter

I printed the desk lamp variant of the Pendant lamp shade by Syphander. The lamp in the picture is Syphander's design, it is not mine. I found that when i placed it on my lamp, it revealed the under side of the lamp, which i thought was ugly. I created this quick model to fix this problem. It basically lets the lamp sit lower, which hides the black portion of the lamp. This fits the pendant lamp shade that has a hole of 43mm. The thickest part of my lamp (under where the bulb goes) is about 38mm wide. This design should fit if yours is 41mm or lower. The top lip's opening is 35.5mm wide. Make sure this size works for your lamp.I created it in two sizes: 40.4mm and 30.4mm. You can change the sizes in the file.
