I 3D printed a holder for the Beckman Coulter HHPC 3+ particle counter so that it can charge and be run simultaneously. This holder screws into the particle counter and into the optics table so that it doesn't tip over. There is also a taller prototype version which doesn't screw into the table in case wires that plug into the particle counter are too tall and stiff.
Attached is the good version of this 3D print as a SolidWorks and STL file and the previous version only as an STL file. I did not recreate the particle counter in SolidWorks. If I were to 3D print this again, I would increase the internal radius on the design to create a more snug fit with the particle counter. This is because the particle counter only has 1 available hole to use. Note: supports were used in the 3D print.
