This is a model of the optical filter holder used in BD FACSymphony instruments, it holds (2) 25mm x 25mm square filters. It is useful if you desire to have a custom filter set for your flow cytometer, and do not want to purchase it from the company.

For fidelity of details, the primary body is printed in 3 parts: Main Body, Mid Body, and Handle. I suggest using glue to assemble them together, how they fit together should be self-evident.

You will have to source 4 short screws to attach the two plates that hold the filters in place. I'm not sure the exact size.

Designed in Fusion 360. f3d file is included if you wish to mess around with it.

Here is a video of an assembled model if you are interested (assembled with junk filters, hence the crack >.<): https://youtube.com/shorts/-A1mncjgJX0?si=Jh2AsBCGit2d8Twz

Print Settings:

• 0.4mm Nozzle
