The Ultimate Tool for 3D Miniature Supports
Engineered by miniature support professionals, Runebrace delivers an uncompromising workflow with powerful, intuitive features for the perfect print.

Key Features
Designed by professionals who have been creating supports for Artisan Guild miniatures for 76 releases. Runebrace integrates all the essential features born from direct, continuous field experience for a workflow without compromise.
Model Preparation & Analysis
Intelligent Auto-Orientation
Find the perfect print angle with a single click. Runebrace's algorithm analyzes your model to find the optimal orientation that minimizes islands and reduces the need for heavy supports.
Advanced Hollowing & Voxel Inspection
Hollow your models with a system built on a powerful voxel engine. Runebrace offers more than just hollowing; it provides an advanced Voxel Editor for in-depth analysis. Navigate freely inside your hollowed models to inspect every internal detail, allowing you to troubleshoot potential issues related to complex geometries before you ever press print.
Advanced Scaling System
Scale your models with unparalleled control. After scaling the main model, the tips and sections of your supports retain their original, effective size. You can then apply non-destructive, percentage-based scaling to each support section (tip, body, base) independently.
Island Detection & Navigation
Runebrace uses modern multi-core CPUs to quickly identify unsupported areas. This helps you find and fix mesh imperfections that can create unnecessary islands, saving resin and reducing supports. A new island navigation and visualization system lets you instantly select any island on any layer.
Interactive Slice Preview & In-Place Editing
Go beyond simple viewing. Inspect your model layer by layer and, crucially, add or edit supports directly from within the slice preview, even on hard-to-reach internal surfaces.
Mesh Smoothing Brush
Fine-tune your model's surface before printing. Use the integrated smoothing brush to gently soften mesh artifacts or blend details without leaving the application.
Advanced Support System
Flat & Smooth Normal-Based Placement
Gain ultimate control over where your supports are placed. Runebrace allows you to switch between placing supports based on the raw, flat normals of the mesh triangles or the visually smooth, interpolated normals. This ensures perfect, intentional placement on both hard-surface geometric details and complex organic curves.
Smart Bracing System
Create rock-solid support structures with a single click. Our smart bracing algorithm intelligently adds only logically necessary reinforcements to prevent tangles and waste, maximizing stability without cluttering your model.
Procedural Line & Arc Fill
Instantly generate supports along straight lines or perfect curves. Select two supports to fill the line between them, ideal for reinforcing long edges. Or, select three supports to define a 3D arc; Runebrace will calculate the precise curve and populate it with supports, perfectly following the contour of rounded bases.
Dynamic Symmetry Plane
Ensure perfect symmetry on any model, regardless of its orientation. Define a custom symmetry plane by simply selecting two corresponding supports on your model. Runebrace instantly calculates the reflection plane between them. Once active, every new support is automatically replicated on the opposite side, guaranteeing a perfectly symmetrical result while cutting your workload in half.
Advanced Support Editing & Dynamic Branching
Effortlessly place supports with intelligent assistance, then modify them with simple clicks on tips, attachment points, or support columns. Quickly reorganize your support network with just a few clicks to find better connections and reduce complexity, especially in dense areas. The intuitive workflow makes it easy to optimize support placement and untangle dense clusters of small supports.
Precision Pathfinding for Supports
Reach any point on your model. Runebrace uses a precise pathfinding algorithm that allows supports to navigate through complex geometries, ensuring even the most difficult areas are perfectly supported.
Flexible Support Editing
Take direct control of your supports. Intuitively click and drag support tips and bases to fine-tune their placement and connection points on the model and the build plate.
Smart Selection Tools
Work faster with powerful selection tools. Use box selection or instantly select all supports that match a specific type, allowing for efficient bulk edits.
Smart Grid Optimization
Automatically consolidate overlapping supports with intelligent grid snapping. Multiple supports in the same grid cell are merged into a hierarchical structure: the tallest becomes a main pillar, while others transform into attached branches. This dramatically reduces resin usage while creating a stronger, interconnected support network with lightning-fast bracing generation.
