Say hello to Nibbler, the tiny HeltecV3 powered “pocket” Meshtastic powered node.


My popular Bender case was designed to be a desk/windowsill node (although it’s still quite pocketable!) Nibbler is designed to be a companion to Bender (this is a Mesh network after all!) with the design goals being maximum portability, practicality, antenna flexibility and all day battery life.

Nibbler Pocket features an internal antenna to give the most compact node possible, while Nibbler Plus features an SMA connector for using the antenna of your choice.

Nibbler Pocket measures 73x46x26mm while Nibbler Pocket is 77x46x26mm. Both have option belt clips in the file! (The clips are super strong)

For extra security Nibbler also has a strong lanyard slot which will accept a loop, a simple black lanyard with quick connector is available in a hardware kit available HERE.

Nibbler uses a 2000mah flat LIPO cell that can provide over 20 hours of battery life! Your phone battery will die before Nibbler! Using this battery is only possible with an adapter cable, again this is available in the hardware kit HERE or you can make you own if you like crimping!!

Nibbler has a construction designed to be tough, portable things get dropped after all. The key to this is the “Niblet” on the end of the body which attaches with two M3 Hex bolts. These bolts screw into captive stainless steel square nuts inside the body and secure the front face and rear battery cover and option clip. Again these hex nuts and bolts are in the hardware kit available HERE or you can source them easily yourself. Nibbler will not come apart unless these two hex bolts are removed, accidental disassembly is pretty impossible! I will be publishing a free STEP file so you can design your own Niblets too… N-Type connector anyone?

To summarise the features:

  • Body measuring just either 73/77x46x26mm
  • Support for a EEMB LP103454 2000mah flat LIPO with PCM chip providing 20hr+ battery life
  • Strong Lanyard loop slot
  • Optional Belt Clips (include in download)
  • Access to USB-C connector for charging

Just like Bender, Nibbler is clean and simple externally but features a precision design with a complex internal structure that has taken countless prototypes to perfect. I love Bender but I love Nibbler more and am sure you will too!

The release notes included in the download contain printing instructions and details on the hardware required, the simplest option is to purchase a hardware kit HERE however.


What is PLA Bioplastic?

All our models are printed in a Bioplastic material called PLA (Polylactic acid) that is made from renewable, organic sources such as corn starch or sugar cane. It's classed as 100% biodegradable but is still quite tough and has a melting point of over 170C. It won't deform unless heated to over 70C, but still best not leave a model in the sun for too long!

Why aren't models smooth?

All 3D prints have a texture due to the nature of how they are created, being printed layer by layer. We print using 0.4mm nozzles which allow great detail with a fine texture.
