Before we start
There are a couple of important choices to make before you start printing the parts. And ordering the
hardware and electronics. These are things I also needed to consider during the design and they are
important for the success of the build.
Materials
I’ve printed these lights in both PLA and PETG. At first I expected PLA to be sufficient but with the
build finished I did notice that the led’s get rather hot, even with the heatsinks. I recommend that
you use a material that is capable of handling a bit higher temperatures than PLA. I used PETG in the
final design and haven’t had issues yet.
Electronics
I use a meanwell LPV-35-12 powersupply, it works well and can easily handle both leds. It does
however require you to work on wiring that connects to the mains electricity in your home. If you are
unclear how this should be done, or have no experience handling these circuits I strongly recommend
not to use this or a similar powersupply but instead use a wall adapter that is capable of supplying
the leds.
The LEDs cannot be powered from the printer’s own powersupply. It is already at the upper limit of
it’s capabilities and can not safely handle the additional load from the LED panels.
There are really cheap LED dimmers available, they work but it’s better to use one that is build a bit
better when you plan to use them as additional lighting for filming. The cheap dimmers are likely to
introduce flickering in the video.
Hardware
I made the design for Metric fasteners (DIN 912) . It may be possible though to use Imperial fasteners
that are very similar in dimensions, you can try this but I cannot guarantee that it will work. If it
doesn’t you can use the CAD files that I published to change the design to fit your needs.
I understand that theaded bushings are not as easily obtainable as normal bolts and nuts. Because of
that I Added a slightly modified version of the main body STL file that has a recess to fit a common
nut (DIN 934)
