Realized I needed a light for my work table. Saw some light bar designs for the HSW, but I wanted to have something adjustable that occupied very little space on my wall. This design also allows me to rotate the light out of the way for more space.

I drilled a hole in the housing to run the wires out the back. I didn't include a pre-made hole in the model so that you can make the hole just the right size for the wires you use. 

After a few failures, I had to bulk up the “HSW attachment” piece so that it wouldn't snap under the weight of the fixture. I highly recommend printing this piece at 100% infill. 

The arm and housing files have threaded holes for M5 bolts. I ended up having to drive the bolt through once while unassembled. This made the threads open up a little and allows for the assembly to go together much easier. After assembly, tightening the bolts still exerts enough compression to lock the arms in place. 

I've included a file for an extra arm if you need to lengthen the light fixture. I didn't need this extension, so I am not sure how functional it will be. I've additionally attached the f3d file, so you can customize to your needs. 

 

Hardware:  - (2x) M5x20mm bolts

                    - (1x) M5x30mm bolt (for “Arm 3” to attach to the thicker “HSW attachment”)
