Adjustable Leveling Plate – Precision Flat Surface for Drone IMU Calibration & Workshop Use

Description

This adjustable leveling plate is designed to create a perfectly flat reference surface using adjustable feet.
It was originally developed for IMU calibration on drones, but it is equally useful for many other precision tasks where a level surface is required.

In the original setup, the adjustable feet are mounted to a plywood sheet using screws, providing a rigid and stable base.
However, the design is flexible and allows the feet to be mounted to other flat materials such as a metal plate or a glass sheet.
When using smooth, hard materials, the feet can conveniently be attached using strong double-sided tape, making the setup fast, reversible, and non-destructive.

By adjusting the feet, the platform can be precisely leveled using a spirit level or digital inclinometer, making it ideal for calibration, testing, and setup work.

Use cases

• IMU calibration for drones and UAVs.

• Sensor calibration (gyros, accelerometers, compasses).

• Electronics assembly and testing.

• Workshop leveling tasks.

• Photography, scanning, or measurement setups.

Features

• Adjustable feet for precise leveling.

• Compatible with plywood, metal, glass, and other flat surfaces.

• Can be mounted using screws or double-sided tape.

• Stable and rigid design.

• Easy to print and assemble.

Printing notes

• Tested and printed with Hyper PLA 0.12mm, 3 perimeters and 15% infill, which proved to be more than sufficient for rigidity.

• No supports required.

• Increase infill or wall count if you plan to use heavier reference plates.

• Threaded inserts or printed threads can be used depending on preference.
