Model Description: A depth gauge designed for measuring hole depths with a minimum diameter of 5 mm.

Purpose: Used for accurately determining the depth of various holes, useful in metalworking and other fields.

Construction Features:

Made from plastic using 3D printing.
Includes a square-section depth probe with a millimeter scale for easy measurements.
The project consists of four parts: main block, depth rod, clamp, and knob.

Printing Recommendations:

It is recommended to use PETG with a layer height of 0.16 mm and 90% infill for the main block.
Print the depth rod in two colors of PETG at a layer height of 0.12 mm for better scale readability.
Print the clamp and knob at a layer height of 0.08 mm for precise thread reproduction.
No support is required, but it is advisable to file the holes with a square needle file to remove rough edges.
