Nobile Kitehandle V3
Client: Nobile Kiteboarding
Custom kiteboard grab handle designed for Nobile Kiteboarding. Multiple design iterations with clip-based mounting system, 3D printed in PETG for real-world testing in Egypt and Poland. Final STEP files delivered for injection molding production.
[about the project] ///
Nobile Kiteboarding needed a custom grab handle for their kiteboard line. The existing off-the-shelf handles didn't match the board's geometry or brand aesthetic.
I designed a handle from scratch in Fusion 360 — parametric model with a clip-based mounting system that locks onto the board rail without permanent modification. The handle extension component connects via press-fit pins (ø6.1mm).
Multiple iterations were 3D printed in PETG and tested at kiteboarding sessions in Egypt and Hel (Poland). The design was validated under real conditions — salt water, UV exposure, high-impact loads during grabs.
Final deliverable: production-ready STEP files for injection molding tooling, plus technical drawing documentation (A3 format) with full GD&T dimensioning.

[process] ///
01
Brief & Geometry Analysis
Received board CAD files from Nobile. Analyzed rail profile, mounting constraints, and ergonomic requirements for grab handles.
02
Parametric CAD Design
Designed handle and extension components in Fusion 360 with full parametric control. Clip-based mounting system designed for tool-free installation.
03
Rapid Prototyping (FDM)
3D printed prototypes in PETG — multiple iterations refining ergonomics, clip tension, and structural integrity. V1 through V3 evolution.
04
Field Testing
Prototypes mounted on Nobile boards and tested at sessions in Egypt and Hel, Poland. Validated salt water resistance, UV stability, and impact performance.
05
Production Documentation
Delivered STEP files for injection mold tooling, A3 technical drawings with GD&T dimensioning, and manufacturing notes.
