Accessories

This collection of accessories are compatible with the Rivian Cup Holder clips.  I recommend using the “stable” window clips (e.g clip-window-1st-row-stable) to have them at your fingertips while driving. Additionally, they're useful mounted along the edge of the front storage area.

You can also use these with my Molle panels using the appropriate adapters (twist-lock-nut +  twist-to-cup-adapter).

Radio Accessories

• Rocky Talkie Expedition (5w) radio cradle

  • The belt clip provides extra stability by sliding over the back and “snap” into a notch, but is not required.

• Rocky Talkie Mountain (2w) radio cradle

• Baofeng UV-5R radio cradle

  • Includes notches that “snap” into place (using the grid texture on the side of radio) to keep it firmly held.

  • The baofeng-uv-5r-belt-cradle version allows room for the belt clip on the radio and raises the mount position so the radio sits a little lower.  This uses the same notches on the frame to hold the radio.  The belt clip is not required, just compatible.

• Baofeng AR-5RM radio cradle

  • This is the larger brother of the UV-5R (wider, deeper, taller) and the mount is tailored specifically for the AR-5RM dimensions.  It includes a space to accomodate the belt clip.  If you'd like a "slim" version without this, let me know.

• Baofeng UV-5RM-Plus radio cradle

  • Similar to the UV-5R but wider, deeper, and with an extra bump for the battery.

  • Thanks @pk_890773 for helping get this dialed in!

  • NOTE: The AR-5RM seems very similar in size to this.  The AR-5RM model is more polished, IMO, as I actually have that radio here to test with myself.  If you have a UV-5RM-Plus, I'd love to know if the AR-5RM version works and if it's a better fit!

• Motorola T470 radio belt clip mount

  • Uses the belt clip tension to “snap” into the final position and hold it firmly in place.  Does not “hook” onto anything.  It pulls back out with just a bit of force.

• Cobra CTW285 radio cradle

  • This slides into the cradle as the arms flex slightly and the belt clip snaps into a notch to hold it into place.

• Generic microphone mount

  • NOTE: This is largely untested, so it will likely change once I have something to test against.

Other Accessories

• Coat Hook

  • Print on side for maximum strength.  Most of the overhangs are small bridges, but you'll need to add tree/organic supports here:

    

• Ball mounts

  • 17mm and 20mm.

  • Print upright with supports on flat bottoms.
