RigExpert Stick model antenna analyzers dry box tray insert protector/organizer

Wether you build antennas or just tune them for use, an antenna analyzer is a useful tool. Over the years, I've owned several, including units by MFJ and Comet. I've also tried Nano-VNA, which are fine but have a steep learning curve.

Over the last 10 years, I've owned 4 different models of RigExpert. They keep offering new features and I keep trading up to get them. I am currently using a RigExpert Stick XPro that works up to 1GHz (so can be used on Meshcore/-tastic antennas) and has a Bluetooth interface to phone app for getting data out. I can't say enough about how well these work and how easy to use these are.

The Evergreen Cases Seahorse SE56 is a commercial, heavy-duty dry box. This size is perfect for the RigExpert Stick line. These water-tight boxes include a key & lock, are IP67 waterproof, and crushproof made from impact-resistant polycarbonate. As of late 2026, you can get these for about US $25-$30 from online retailers. I reccomend the version with egg-crate foam lined lid.

I tested this design with a RigExpert Stick 500 (my last one) and a RigExpert Stick XPro, but it should also work with the RigExpert 230 and RigExpert Pro models since they have the same form factor.

This design is similar to one you can find on eBay that sells with the box for about $75 (not wanting to detract from the eBay seller, so if you can't print your own, please go buy his). I bought one of those from eBay about 3 years ago when I got my first stick and it's a fine/functional design. I used it for 2+ years before contemplating customization.

The eBay model is not compatible with how I use/store my RigExpert (with N-UHF adapter attached - for reasons), was printed in PLA, and didn't have enough storage for connectors (I carry more than 7, as you can see).

Since purchasing this, I started designing my own things/parts and 3D printing for my many varied hobbies. This is my own AutoCAD 2027 design - from scratch.

My design criteria:

• Accommodate the RigExpert to be stored with the N-UHF adapter attached

• Provide for organized storage for my connectors, customizable

• Provide a way for the lanyard pigtail to store in the accessories box area

• Print from more rugged material

I have included multiple design options for different configurations of open accessory storage wells and connector holders. I have also included several options with "blank" connector areas that you can customize using negative primitives (cylinders) in your slicer to meet your needs. I've provided a 3mf file with negative primitives attached to a cube that you can insert and copy/paste to the tray you want to use.

The tray mounts in the box with (4) M2x10mm coarse self-tapping screws (or machine screws if that's all you have).

I printed on Creality Hi using OrcaSlicer with 0.16 layer height, 4 wall loops, 5 shell layers, Arachne walls, and 10% adaptive cubic infill. Supports not required. Since this might sit in my truck on hot days, I printed using PETG (my "go-to"  material for radio stuff) for thermal resistance, and good-enough UV-resistance, impact durability, and moderate flexibility.

Notes: If you need the Evergreen box CAD files, they are available here from GrabCad.

P.S. if you curious why I store my RigExpert with the N-UHF adapter attahed, it's becuase I had a self-inflicted wound a few years ago. I had an AA-230 Zoom and this model also has an N port standard, not a UHF. I owned it for maybe a month (after coming from using an AA-54 with a standard UHF connector). I absent-mindedly tried to force a UHF adapter onto it - and figured out my mistake after the damage was done ... that was a very expensive repair. For reference, RigExpert doen't use standard connectors and are very specialized. Note to self: use caution when putting on connectors!
