Summary
Remix details:

I used the Lenbok Redox-rev0b fork of the case as a starting point, modified all the ports within OpenSCAD, made my changes in Fusion360 to fit the display and the trrs hole
Original work

My Remix(by now there are only the modification on openscad side, i will add dwg of the display)

Firmware --> https://gitlab.com/neodox/neodox/
just clone it into this qmk path keyboards\handwired\
then follow the readme.md instruction in the root of my firmware repo.

GP23	WS2812	data pin for rgb leds( also called neopixel)
GP25	LED RESET	noting to do ,usually every rp2040 controller board is wired to a led
GP28	BLK LCD	backlight pwm for the lcd

Notes:
GP5, GP15
this intersection is used to define handness( which of the half is, right leave it not connected on the left side, connect a diode as a continuosly pushed switch, this is possible because we have some hollow intersection that we didn t use physically in the matrix 7x5)
diode direction col to row(cathode)

The differences are:

a trrs jack for connecting the 2 boards
no reset switches, I use a qmk bootloader keycode
the plate is 2mm higher respect the redox handwire from Mattia but it`s less prone to bend
removed two keys (so 4 in total) to fit the TFT screen gc9a01
( around there are two major designs of this display I use the one with the rectangular pcb,remove the strip if the display comes with it)
M3 x 5,7 x 46 mm insert compatible, M3 10 mm screws
