(Note: The original file names are in Turkish. "Kaya saplaması delik deneme" translates to "Rock Bolt Hole Trial".)

This model is designed to represent a mining-type rough borehole for rock bolt applications. It features a specialized inner texture to simulate the mechanical interlocking (interlocking) between the grout, the bolt, and the rock surface.

Special thanks to Stefan from CNC Kitchen for his incredible work. This model was processed using the Bumpmesh.com tool to achieve realistic surface roughness.

💡 Slicer Tip:

When using the final STL file (Kaya saplaması delik deneme_Crystal_amp1p00.stl), please right-click the model in your slicer and select "Split to Objects". This will allow you to manage the split parts easily for a flat-on-bed printing strategy.

Technical Specifications:

Dimensions: 70 mm Outer Diameter / 24 mm Inner Hole / 100 mm Length.

Compatibility: The 24 mm hole is specifically sized to accommodate a standard 12 mm rock bolt (rebar), leaving realistic clearance for grout and drilling tolerance.

Magnet Pockets: Designed for 17.2 mm magnets (17.5 mm diameter / 3.3 mm depth).

Texture Details: Amplitude 1.00 mm / Scale U-V 0.3 (Cylindrical Projection).

File Formats:

I have included STL and 3MF files so you can print it immediately or use them in your slicing software.
