[FAFO modified version]
### FAFO Modifications
- We are using a different lens (Thorlabs `CAY046`). This lead to the need to change the mechanical dimensions quite a bit.
- We are aiming to build the module using a 623nm red laser diode.
- Our module is longer to achieve good coupling efficiency with the selected fiber and lens.
- A bit wider for the bigger lens diameter.
- We are using a 635nm red laser diode.
- The lid has M6 mounting holes for optics breadboards.
