OmniLevel: 3D Print Bed Leveler

A tool that helps makers and professionals level their FDM-based 3D Print Bed

Overview

Do you ever find it a hassle to manually level your 3D print bed every time you make a print? Even seasoned 3D printing pros need to level the printbed after every couple prints. We’ve created a device that helps tremendously improve this procedure. This project, codenamed OmniLevel, helps you level your 3D printer bed with just a push of a button. We used the M5Stick-C to monitor the pressure between the nozzle of an extruder and the printer bed. Using a force sensitive resistor (FSR), this allows the user to easily detect when the bed is level.

Supplies and Materials

For this project, you will need the following materials:

• M5StickC - $25 on Amazon
• Male 8-pin header - $1 at Parts store or salvaged
• Round Force-Sensitive Resistor (FSR sensor) - $7 on Adafruit
• 10k Ohm Resistor - $0.50 at Parts store or salvaged

Overall, it should cost you less than $40 to build.

It is highly recommended that you have the following supplies:

• Wire Strippers/Cutter
• Soldering iron w/ solder
• Tweezers
• Hot glue or UV glue (to isolate connections)
• A piece of large heat-shrink (to protect the circuit)
