Coworker and I designed a fixture to solder WS281x LEDs into matrices and strips! Should be pretty useful!
Good idea. Let us know how it works out.
Nice, curious to see how this works.
That’s great!
Say…would you maybe consider sharing a file that I could convert to STL?
I would love to print one up for my bench…I could have used that for sure on my last project.
@Jon_Bruno how accurate is your 3D printer? It’s designed to only have .005" of clearance on each side of the LEDs and buss wire at every place on the fixture. I’m going to CNC machine it out of 1018 steel or something similar.
@Kyle_Halvorson Just a curiosity, what did you model it in? The background grad reminds me of FreeCAD.
Wow, steel, I guess that fixture will last a lifetime then.
We used onshape. Cool software, it’s browser based and free so anyone can use it anywhere, even on your phone! Also, it was developed by the people who make solidworks so it’s pretty similar.
And yes, it should last a while. 
My machine should be able to come up with something pretty darn close to it.
.005 is plenty of space.
Lol…
Oh wait… Is this for soldering the raw die packages or the disk mounted jobs?
It’s for soldering LEDs into strips and matrices, the blue squares on the CAD drawing are the LEDs. No PCB involved.
Oh excellent, yes I love Onshape. (I used FreeCAD before I learned about Onshape.)
What format will you export and to what CAM software? I want to be able to do this myself someday so am very curious to learn from others what process they use.
I not sure what format but I believe we’re going to use esprit for the CAM, I work at a machine shop and this is all stuff I want to learn to do myself anyway.
This is one reason I’m working to be a machinist, so I can make my own products and sell them. I have many other ideas I’m going to design and make.
