Description
This is my first project of this scale and it was an amazing experience building this, i got to learn a lot!
I would like to thank hackclub's hackapad tutorial, Joe Scotto and Google, you guys were my saviors.
The keyboard is a tweaked default 65% layout with one key replaced by a RE. The MCU used is Raspberry Pi Pico and the firmware used is kmk.

Grand Total
The total sum of the parts comes to approximately inr 12335 ($141.5).
I have chosen air registered mail as the shipping option for jlcpcb as it's less likely to incurr customs thus actually being cheaper than other shipping providers.
PS: i have also included an additional USB hub and 2 microusb to type A cables because of the macropad and keyboard i wont have any space to plug the gadgets into my laptop
Note: TOP and BOTTOM case parts in white, MIDDLE in black; PCB must be white.
Some componenets were ordered in packs due to unavailability (bolts, heatset inserts, etc), their prices may vary due to sales.

Questions
How big is the Keyboard pcb PCB?
It measures 308 × 126 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keyboard pcb use?
154 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Keyboard pcb KiCad files?
From the Midaah-r/keyboard repository on GitHub, at the commit this page was made from: the board is PCB/keyboard_pcb.kicad_pcb and its schematic PCB/keyboard_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Keyboard pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask Midaah-r before reusing the design.
