3D Printer lamp

I created this lamp to be mounted on top of my printer to light up my build plate. I designed this lamp to be light and to be a “set and forget”. 

It is made up of four elements : 

• The base, to put on a 20*20 aluminum extrusion. I used 2 * M3 screws and T nuts to secure it on both sides of the extrusion. The holes for the screws are recessed, so I suggest you use short screws.  
• The lamp, on which you can put strips of LEDs. 
• The link, to link the lamp and the base. You can use multiple of these. I used 3. 
• A screw and a nut, I only used it to attach the last link with the lamp. 

The link can be printed as presented without any tweaks. For the base, you can print it with the “V3” standing right side up and use support for the legs and the holes for the screws. For the base, you can print it with the “lighting” face on your build plate and use support for the mounting legs. I printed every part with a 15% infill. 

Regarding dimensions, you'll find a screenshot of my original drawing for the link, the link is 10 mm in width and the legs for the lamp and base are 5 mm thick. 

Since I wanted it to be as light as possible, I tried using the 3D printed screw and nut, but it was way too fragile for this application. So I used 8 mm by 30 mm metal screws and locking nuts to hold the links together. For the lamp, as said earlier, I still used the 3D printed screw to be able to rotate the lamp since it doesn't need to be really tight. 

Regarding wiring, I included a small hole in the upper left corner of the lamp. I used 22 AWD wires for this, so it could be a little too small depending on what you have. I wired my strips by hand. I chose to use 24V white LED's (they are really bright, so I suggest you use some kind of dimmer like these : here) and I wired it directly to my printer's power supply (which is 24V).
