Custom Climbing Wall Holds - 3 Crack Cruxes

Welcome to your next project! This is a set of 3 procedural crack climbing holds designed to create the perfect "crux" for your home climbing or bouldering wall.

These holds feature a dynamic internal geometry that simulates real rock cracks, complete with pinches, pockets, and a generated fuzzy texture for maximum friction.

### 🧗♂ Infinite Variations with OpenSCAD

The true power of this model lies in the included crag.scad source file. You are not limited to just the provided STL files! By using OpenSCAD, you can easily modify:

* Hold Depth & Dimensions: Adjust the size to fit your wall and hand size.

* Crack Geometry: Change the number of pockets, pinch width, and crack meandering.

* Mounting Holes: Easily adjust the screw hole diameters to fit your standard local hardware.

* Texture Intensity: Dial in the perfect amount of internal grip texture.

Included STLs for immediate printing:

* crag-01.stl

* crag-03.stl

* crag-menejstrmy.stl

* crag-treti.stl

### 🛠 Hardware Requirements

* Standard wood screws for climbing walls (adjust the hole diameter in the .scad file if needed). Ensure screws are long enough to pass through the hold and bite deeply into the wall.

# 🖨 My Print Settings

Climbing holds endure dynamic loads, so structural integrity is key. I have personally printed and used these holds on my home wall with the following setup without any issues, but you should adjust according to your specific filament and printer capabilities.

* **Material:** PETG (Recommended for its impact resistance).

* **Perimeters / Walls:** 5 perimeters (Crucial for strength around the screw holes).

* **Infill:** Gyroid (Provides excellent multi-directional strength).

* Orientation: Print flat on the back.

# ⚠ Safety Note

While I have personally climbed on holds printed with the settings above without issue, please remember that climbing is an inherently dangerous sport, and 3D-printed parts can behave unpredictably depending on the material, printer calibration, and environmental factors.

By downloading and using these models, you accept all responsibility for your own safety.

* These holds are intended for personal home bouldering walls and should be mounted over proper crash pads.

* I do not recommend using 3D-printed holds for high-wall lead climbing or roped routes.

* Regularly inspect your holds for signs of wear or micro-cracking around the screw holes.

Have fun, train hard, and climb responsibly!
