A set of trays for organizing my coaxial adapters and connectors.  These trays can be stacked freely and fit a 2x3 Gridfinity space.

I made separate trays for small, medium, and large connectors.

To give some ideas on the possibilities

• The SMA tray, I use with small SMA/SMB connectors, loads, and inline SMA filters and attenuators
• The BNC tray fits things like BNC adapters, loads, and F-type connectors.
• The N-type tray is used with N connector adapters, UHF/PL259 adapters, and APC-7 adapters and attenuators

The tray for the large connectors is 4 Gridfinity units high, the others are 3 units high.  I've printed mine in PETG-HF, but PLA or any other filament should be fine too.
