InclinoCar Core Case and mounts

InclinoCar — Rooftop Tent Leveling Assistant

Introduction

InclinoCar is an open-source device that helps you level your vehicle when setting up a rooftop tent. It reads pitch and roll from an IMU sensor and shows them in real time on a display, plus streams the data over Bluetooth to a companion Android app with a bubble-level view. Park, glance at the readout, adjust your leveling ramps, done.

This model set contains the printable enclosure and mounting hardware for the ESP32-C3 "Core" unit. The electronics, firmware, and app are all open-source — the full project (with a browser-based firmware installer, so no toolchain needed) lives at:

What's in this model

• Core Case — three parts: Box, Lid, and Clip

• Mounting brackets — including a set tailored for the Taktältarna Åreskutan 2.0 tent, plus a powerbank holder

• Mounting brackets — alos one for the M%Stick, booth C plus and S3

What you need to build the full device

This is the enclosure only. To build a working unit you'll also need the electronics (all wired on a shared I2C bus):

• ESP32-C3 Super Mini

• SSD1306 128×64 OLED display (I2C)

• MPU-6050 (GY-521) accelerometer/gyroscope

• Momentary push button

• Silicone jumper wire (26 AWG)

Full wiring diagram and parts links are in the GitHub README.

Build / assembly instructions

1. Print all parts — Box, Lid, Clip, and your chosen bracket.

2. Flash the electronics first. ⚠ Flash the ESP32-C3 before assembly — the case has no access hole for the BOOT button once closed. Use the browser installer: open https://tophe75.github.io/inclinocar/ in Chrome or Edge, select ESP32-C3, and Install.

3. Wire the components per the GitHub wiring diagram (OLED + MPU-6050 share SDA=GPIO6 / SCL=GPIO7; button on GPIO5).

4. Seat the electronics in the Box — first the MPU, place a 10mm PTFE tub on top then the esp32, line up the clip and mount the button to secure everything.

5. Fit the display onto the box — fit the lid over it and secure with 4 M2x6mm screws.

6. Mount using the bracket for your setup; the powerbank holder if you need it, goes together with M3 screws.

7. Calibrate — off the vehicle on a level surface, hold the button 1 second or use the android app.

8. Done.

Print tips

• Avoid PLA. A closed car in summer easily exceeds PLA's softening point and the case can warp or sag. PETG is the sweet spot — tough, heat-tolerant, easy to print. ABS/ASA is even better for heat and UV if you can print it cleanly.
