(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. Credits & Attribution: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.
