Overview
Driver is an open-source printed circuit board by Caraffa-git, from the Caraffa-git/LM3410X-Laser-Driver repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board with 10 parts on 6 nets, routed with 18 tracks and 26 vias.
It is built around the LM3410XSD, SS0540 and XFL3012-104MEC. Its parts include 2 capacitors, 2 resistors, 2 diodes, 1 IC and 1 inductor.

README
README.mdLM3410X Laser Driver
Constant-current laser diode driver based on the LM3410X, designed primarily for TO18 laser diodes with high threshold voltages. It was originally intended for relatively low-power Sharp GH04850B2G 488nm laser diode, but with appropriate inductor, it can handle significantly higher currents. The board measures 10 mm in diameter and fits into standard 12 mm TO18 laser diode casings.
Hardware
Design uses a compact 3 mm XFL3012-series inductor from Coilcraft, available in a wide range of values to suit different target currents. Impornat note - saturation current of the selected coil can't be too low. During startup it is possible for the inrush current to saturate the core and lock up the driver IC.

This is essentially a flashlight I designed because I wanted to use some free parts from TI. This uses the LM3410 driver to boost the voltage of the LiPo battery and drive the LEDs at a constant current.

Questions
What parts does the Driver use?
10 parts, built around the LM3410XSD, SS0540 and XFL3012-104MEC. 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 Driver KiCad files?
From the Caraffa-git/LM3410X-Laser-Driver repository on GitHub, at the commit this page was made from: the board is hardware/driver.kicad_pcb and its schematic hardware/driver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Driver design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
