This is a detailed compact flux Capacitor 190X140X70. Built it in a Gewiss GW44207 box
I scaled the relays from RadBench flux capacitor.
As seal grommet on the cover you can buy it (like this https://www.mcmaster.com/3275t22/)
or print

BOM mecchanical part:
-GW44207 box
-2 srews to fix the plate
-3 srews to fix the relays
-25cm yellow cable d= 0.5-0.8mm
-19x140 transparent acrilic foil 1\2mmm thick
-20cm spun iron d=1mm
-transparet pla\petg
-red pla\petg\abs alternativelly you can paint the parts
-black pla\petg\abs alternativelly you can paint the parts
-golden or copper pla\petg alternativelly you can paint the parts
-transparent acrilic foil
-15cm transparent tube d=4mm like this (https://it.aliexpress.com/item/1005004297773733.html?spm=a2g0o.productlist.0.0.187973b6z8XG75&algo_pvid=1f9ca032-eaa3-4796-9413-d504fa97e901&algo_exp_id=1f9ca032-eaa3-4796-9413-d504fa97e901-2&pdp_ext_f=%7B%22sku_id%22%3A%2212000028672264869%22%7D&pdp_npi=2%40dis%21EUR%211.25%210.75%21%21%21%21%21%402100bddf16648159916304852e731b%2112000028672264869%21sea&curPageLogUid=YDSlxbUFoPGt)

BOM electronic:
I used the usb 5V as supply power so for leds i used the parallel configuration then each led as an resistor, if you use 12V supply you can use the serial configuration to save componets becouse you can use only one resistor for each "ring".

-1 arduino nano
-5 mosfet n-channel
-5 10k resistor
-5 33ohom resisto
-12 warm light leds
-5 white ultra bright led (for time travel fx)
-a IR remote control (for fx control)
-1 IR receiver tsop3328 or similar
-1 switch (for power on)
-1 mp3 player uart module for sounds
-some wires and comb connectors

Tools:
-dymo junior for labels (alternativelly you can print it)
-hot glue or similar

PRINT NOTE:
print with TRANSPARENT PLA\PETG tubo vuoto3x and cristallo 3x
print RED cappuccio 3x or paint it
print BLACK pannello 1x and 1x myseal or paint them
print golden or copper tappo3x and cilindrofull3x or paint it
print 4x screw cap if you want and paint in the same color of box

TIPS: for protect the switch you can print this flip switch cover by by @GiovaGio
