I don't have alternative software yet, waiting on the MQTT implementation before I start mucking about with software.

I have uploaded files to Thingiverse, referencing the first file and this site.  https://www.thingiverse.com/thing:3364217

Changes so far:
  • Cut holes in the diffuse faces on the base. This removes a substantial quantity of material while leaving plenty of room for gluing down thick tinfoil or other reflective surface.
  • Hollowed out underside in some areas, added chamfers.  Should print without supports.
  • Minor edit to the top frame. Added in holes for sewing fabric to the front for a different look.
  • Created two sizes of panel joining I-pieces. One that would allow flush fitting of panels, and one with a 2mm gap for upholstered front panel fitting.

As my printer (200mm square bed, with only 180mm usable area) can't print the pieces as one, I have also included split pieces.  Maybe not optimised, but split.  I may revisit the splitting of the top.

My plans, and if others have experience of the same, please let me know if these ideas are bad:

  • Sew a white or white+light patterned fabric to the front panel.
  • Glue tinfoil or acrylic mirror to the diffuse surfaces in the base
  • OR
  • Paper-back the tile bottom, infill with low-density cotton or polyester stuffing

I will start printing over the weekend, my printer needs repair, plus I only have grey filament.  I am not relying on the filament for any diffusion.

As a bonus crazy idea, place 3 LED in each corner, reduce panel count/increase power supply, and create a quilted upholstered top to sew on.  I may need to do the 3 LED per corner, as the strip I have on hand is not individually split, but if I do a software edit and cut power to each LED to 1/3, I can probably maintain the same peak power requirements.

If I can be bothered, here is a list of further improvements I would want to make.
  • Add in capacitor across 5v/Gnd
  • Place and program a status WS2812B in the power bottom, wired as per a Hackaday article to get a 5v data signal out
  • Add in a power switch to cut power to the LED strip while leaving NodeMCU powered
  • Accessible reset button and USB socket

Edit:Added in a bit extra detail.

Love seeing all the ideas, please post your results.  A couple of us have tried a reflective base, however it didnít seem to help but maybe with your other mods it will. I also tried throwing some batting inside to diffuse the light, but again it didnít help.   The three lights per corner is definitely a good option and will brighten up your panels.
Welcome to the group and happy making...

    THANK YOU!  Noticed this design feature existed in the tile bottom design, but no clips have seemingly been discussed or included.  Glad I'm not crazy and that others saw a used for them!

    When I was looking through, I had the same thought, there were slots, but no connecting pieces.  I have designed them, but haven't printed them yet, so I don't know if they actually fit.  They've been set up with a 0.2 mm margin, might be too loose or might be just right, don't know.

    I am going to be looking at doing more editing of the components as there is not a socket for the I-pieces in the power connection.  Got a few other edits as well, going to edit my first post with the ideas.
