Custom enclosure for an assembled amateur radio RF EZ low pass filter kit from Pacific Antenna. The QRPkits EZ Low-Pass filter kit is a small kit filter with BNC connectors that is for 20m, 30m, 40m, or 80m amateur radio bands. It does not come with an enclosure, but this box will work to give you some ruggedization of the filter. This does not reinforce the connectors, and it is not at all sealed. Minor fitment and filing was still needed. The file "pacific antenna filter box SS.3mf" has my print setup.

How I Designed This ===================

Measured assembled kits and modeled in AutoDesk Fusion 360

I measured board size, BNC diameter, BNC center offset from the board height, and highest component from the board height, the board height (thickness) and the distance between the mounting screws.
Modeled these parameters, printed first copy, revised design and then printed several for my own filters.
