Modulair Diffusion panels with LED lighting!
disclaimer:
Still in the process of figuring out product design, testing and documenting everything this will be a very early concept. currently I'm in version 8 or 9 (can't even remeber/ keep track) but there were a lot of prototypes before this. made many little misstakes and therefor I can't promise there are some flaws left. either way it is good enough to publish. I got one build already and making some bigger ones now to make sure every part fit into eachother.
you CAN use it WITHOUT the LED-strips and just print the diffuser parts. they still connect with countersunk screws to eachother and you can use the existing holes on the front to mount it to the wall directly. cover it with a screwcover located in the files section and done.
Getting started
I made some folders containing everything you need to make the corresponding dimensions. for example; if you want to print a 400x400mm diffuser you print everything in that folder and you're done (take note of the amount to print, it's described underneath)
Details
starting with 40x40cm this is the smallest diffuser you can configure. You only need 4 cornerpieces 200x200 and a centerpiece to lock it all in place.
Now you can make it as big as you want in steps from 10cm. for example you can make a 50x40 panel or a 70x50 or a 100x60. just use the end- or midpieces available.
the whole thing uses m3 5x5 heat inserts
it screw together using various m3 10/18/20/22mm screws
the cornerstones I used some m3 5mm countersunk hex screws
the LEDSTRIP is a 12mm WS2812b and fits into the slot of the profile, no need to waste the gluestrip.
I controll everything with a ESP32 board with WLED installed
I've designed everything to put all the cabling through the wall. I guess not everybody can do this and will be forced to have the cable in sight. I will make another part to house an external cable (it's in the experimental folder for now).
As in the description you can make it any size you want, go in 10cm increments or 20cm everything should fit together. play arround with the different heights of the diffuser blocks. it is designed so it wont have a connecting block with the same height.
print settings:
with these settings it will cost you about:
Diffuser parts:
LEDprofile parts top and bottom:
so for a 40x40 grid you will use about 1100 grams of filament
things to do:
Centerpiece to lock in various extensions together using m3 5mm countersunk hex screws
This looks hectic but is not that complicated.
these small m10 screws are only there to hold the bottom and top of the frame together, as well as giving some structural support.
to make a frame you just need to connect all the m3x10 screws and m3x18 sidescrews to their corresponding others to make a frame. later you will screw this frame to the diffuser
