Summary

A DIY 3D navigator for Blender, inspired by KikiHobbyRepair's SpaceRat (https://github.com/KikiHobbyRepair/SpaceRat).

It uses an MPU6050 3-Axis Accelerometer mounted on a steel spring and a rotary encoder. 8 MX keys and 2 push buttons provide command customization options. Each button can be assigned single and double click commands, as well as hold actions (check attached image). A HID capable board is necessary to convert the key strokes into keyboard commands (such as Teensy 2).

To orbit, simply move the knob while the cursor is on the 3D View (this emulates the movement while the MMB is pressed).

To pan, press and hold the knob while moving (this is the equivalent of holding Shift + MMB).

I recommend setting the "Orbit Around Selection" option in Preferences > Navigation > Orbit and Pan.

The Neopixels flash the Blender colors at startup, and then randomly pick one. The lights can be cycled by double-clicking on the left button (blue > orange > white > off).

Detailed building instructions can be found in (Coming soon).

There are two versions of the bottom lid: A normal one, and one with spaces for washers to add weight while printing (I used the Pause at Height plugin in Cura).

I provide the blend file, as well as the Arduino sketch and Kikad files for CNC milling the
boards for the controller and the LEDs.

Model 2: gyroscope instead of rotary encoder.

I also include the files ("Blender_Model2_gyro_files.zip" with stl and basic sketch) for a prototype using the MPU6050's gyroscope to simulate the mouse scrolling with a twisting motion, completely replacing the rotary encoder. It's just an early concept, feel free to expand on it.
