I couldn’t find a good 3D-printable replacement body for the Digital Harinezumi, and I was always annoyed by how often I had to replace expensive batteries - so I made this.
This version is designed for the Harinezumi v2, but it should also fit the other versions (or at least be easy to adapt with a bit of sanding if needed).
All parts should be printable without supports. The holes and button cutouts include some built-in tolerance, but depending on your filament and printer settings you may still need a bit of wiggling, filing, or sanding for a perfect fit.
The battery compartment at the bottom has space for various battery types. Personally, I went with a Keeppower 26650 (5200mAh, 3.7V), which can be recharged via micro USB through the bottom of the case. You’ll need to route the wires through the connecting holes and solder them either:
-
directly onto the battery terminals (then secure everything with hot glue), or
-
onto spring/contact pads that you glue into the case, so the battery can simply sit between them.
This project is mostly finished. I already have a few ideas on how to improve the design, but for now it works very well for what it is.
Note: this design does not include:
-
the switch to toggle the camera between normal and macro, or
-
the ability to access the menu.
Feel free to add these features if you need them - at the moment it’s essentially a simple point-and-shoot setup.
For access to the microSD slot, you will either need to remove the PCB, or use a microSD extension cable/adapter.
Coil the microSD extension cable underneath the battery and route it out through the top. That way, whenever you want to swap cards, you can simply remove the backplate and access it easily.
And that’s basically it. Just make sure to position the battery so the charging port remains accessible.
