Materials and Print Settings:

• ASA or ABS are ideal due to their resistance to environmental factors and durability.
• PLA or PETG can also be used if the caliper is not subjected to heavy use.
• Use a 0.2mm nozzle for high detail accuracy and sharp edges.
• A layer height of 0.1 to 0.2mm is recommended to ensure precise measurements.

Printing the Vernier Caliper:

• Print the various parts of the caliper separately, including the ruler and the slider.
• Ensure all details are clear and edges are sharp to allow precise assembly.

Assembling the Vernier Caliper:

• After printing, deburr all parts and remove support structures to ensure smooth movement.
• Assemble the caliper by inserting the slider into the guide on the ruler.
• Test the movement of the slider to ensure it moves smoothly but is not too loose.

Using the Vernier Caliper:

• The caliper is designed to measure inner and outer diameters, as well as depths.
• The accuracy of the caliper depends on the print settings and assembly precision.
• Ideally, it allows measurements in the two-decimal-point range.

Maintenance and Care:

• Keep the caliper clean and free of dust and debris to ensure smooth movement.
• Check regularly for loose parts and correct the fit as needed.

Conclusion:

The 3D-printed vernier caliper is a useful and precise measuring tool that can be easily assembled. Its accuracy depends on the print settings and assembly, but ideally, it can achieve measurements in the two-decimal-point range. ASA or ABS are recommended, but PLA or PETG can also be used. With this guide, you can print a high-quality caliper to meet your needs.
