This is alpha version of Ploopy Adept BLE modification.
All necessary files are here but they are still messy.
Document may not reach your satisfaction.
electronics
Designed by KiCAD and produted by JLCPCB
Basically you need XIAO nRF52840 board, PMW3610 optical sensor, omron D2LS-21 mouse switch, 6-pin slide switch and battery.
Other parts are set as below.
firmware
Here includes uf2 file built by zmk.
You can find the code here.
housing
I designed like you only need bottom modified housing additionally.
Note that put the battery wire not to interfere both top and bottom housings.
And you need to cut battery switch so as not to interfere the desk surface.

Questions
How big is the Sensor PCB?
It measures 62 × 64 mm and has 2 copper layers, 1.29 mm thick.
What parts does the Sensor use?
23 parts, built around the D2LS-21. 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 Sensor KiCad files?
From the taichan1113/AdeptBLE repository on GitHub, at the commit this page was made from: the board is electronics/sensor.kicad_pcb and its schematic electronics/sensor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sensor design in my own project?
Its repository publishes it under the CERN-OHL-P-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
