Description
A precision-designed parametric fence post cap engineered specifically for square posts, providing reliable fit, weather protection, and a clean architectural finish.
The model is primarily designed for posts where the cap fits according to the internal dimensions of the post profile.
All key dimensions are fully parametric, allowing easy adjustment for different post sizes and manufacturing tolerances.
⚙️ Technical Features
Fully parametric geometry
(post size, roof width, wall thickness, insert depth)
Configurable roof design
(4-sided pyramid or cone roof)
Optional screw hole for mechanical fixation
Optimized for support-free FDM printing
Designed for durable outdoor PETG performance
📐 Dimensional Logic
Post Size
Defines the internal dimensions of the square post
Roof Width
Controls overhang and water shedding performance
Insert Depth
Improves mounting stability and alignment
Wall Thickness
Affects strength, stiffness, and print reliability
Roof Height
Influences water runoff efficiency and visual appearance
⚠️ Fit & Tolerance (Important)
This model is parametrically designed around the internal dimensions of the post.
If you want the cap to mount over the external dimensions of the post, the width parameter must be adjusted accordingly:
External Mount Formula
Adjusted Width = Post Width + (2 × Wall Thickness) + Tolerance
Why tolerance matters
Real-world fence posts are rarely dimensionally perfect.
Wood can swell, shrink, or warp depending on humidity and weather conditions, while metal or plastic profiles may vary from their nominal dimensions.
Adding a small clearance tolerance is strongly recommended for proper installation.
Recommended workflow
Print a low-profile test ring
Verify fit on the real post
Adjust tolerance if necessary before final printing
Skipping this step may result in poor fitment.
