YET another LED ARC lamp

Like so many others ,I like the LED Bridge Lamp by Opossums. 
There are a few others great designs like: 
this one
this one
this one 
this one 
… and probably a few more
But as usual none of them was exactly, what I was looking for ….. as usual :-(

I also wanted to use strips like this one from BTF Lighting
FCOB SPI RGBW IC LED Light Strip WS2814 Addressable 784 LED

This made the LED diffusor obsolete - :-)

Therefore a controller is needed and I wanted to go with some ESP32 thingy.
But then I found this one: 
GLEDOPTO ESP32 WLED LED Controller With Mic &UART
Comes with all the connectors, has his PSU integrated, has a button 
is sound reactive, in a box,  
has 2 GPIO outputs - great
and all connector on board - even better :-)
… and therefore I think this thing is well worth the money spent!!

I just had to upgrade the firmware from github using this file: 
WLED_0.15.0-b2_ESP32_audioreactive.bin
… because the strip needed “color swapping”

In the “usermod” configuration I had to set the following parameter,
 to make this thing “sound reactive”

The LED setup for this strip is


So here is my solution for a 178cm wide work-desk.
The radius for the ARC where the LED runs is 65cm.
Therefore the minimum width for the whole assembly is is 130 cm +2x3.8cm = 137.6cm.

For my desk I needed a total width of 178 cm so I needed to add ~410mm in the center.
Because printing the ARC extension upright, I had to split the part in 2.

That turned out to be a total height of almost 216.8mm high!!
My old trusty workhorse MK2.5 could not print this high :-( 
… so I had to use my MK3.9 :-)
 
Because of the very low bed adhesion I designed a breakout part to increase bed adhesion.
But that did not work with the standard MK3.9 speed settings.

I added custom G-code to gradually slow do the printer. Every 10mm or so  (M220 Sxx) 
I ended up at only 30% rate at the last 10mm.

Be aware that this print uses up to 2kg of Filament!!

I also used both GLEDOPTO Output (GPIO 16&2) 
therefore almost 2x ~2.4m = ~4.8m LED strip

Attention: test them BEFORE gluing them!

Fusion 360 file included
..have fun :-)
