EDIT: The design has been updated in order to move the bulb's heat sink away from plastic. I slightly melted the lamp stem after having the lamp on for a while. Now that I have been using the new lamp stem I have not had any problems.
I wanted a cool lamp to bring to work and I decided to design this awesome glowing mushroom lamp. I love how it turned out! The lamp shade is printed in red and glow in the dark filament. I designed the lamp around these pendant sockets and LED bulbs. The design files can be accessed on OnShape here, feel free to copy and edit them as you wish.
