Father & Sons Collaboration

Engineered for Ping Pong Parachute & Egg-o-naut

Designed directly from 3 years of hands-on coaching and field testing. Built to deliver consistent launch angles, reliable pressure holding, and repeatable release cycles so students spend their time optimizing bottle aerodynamics and parachutes rather than troubleshooting fittings.

Standard Schrader Valve Bicycle pump & compressor compatible

Rigid Launch Guide Stable 90° and angled flight rails

RELEASE ASSEMBLIES: COMING SOON

We are finalizing the mechanical quick-release trigger. Final photography and pre-order links will go live following current test cycles.

The Kinship Story

Where Engineering Mentorship
Meets Entrepreneurship.

I’m a mechanical engineer by trade, but coaching Science Olympiad events for my 3rd year has been one of the most rewarding engineering experiences I’ve had. Working with students on events like Boomilever, Ping Pong Parachute, and Egg-o-naut showed me how much learning happens when testing rigs are dependable, accurate, and fun to use.

Kinship3D started as a way to share the fixtures we engineered for our own team with other coaches and parents. It’s also a hands-on vehicle for entrepreneurship with my kids: teaching them how real products go from CAD sketches to slicers, physical test plates, and customer packaging.

My sons and daughter help brainstorm, assemble, and—most importantly—test! each fixture until we know it will survive competition day stresses. When you use a Kinship3D rig, you’re using equipment tested by young competitors who know what it feels like to wait for that bucket to fill.

"Our goal is simple: take the frustration out of testing fixtures so students can focus entirely on the joy of discovery and optimization."

WORKSHOP PRINCIPLES COACH VERIFIED

• Iterative Prototyping: Every rig is refined through actual team trial runs before release.
• Full-Load Stress Testing: Assemblies are physically loaded beyond the 15 kg tournament maximum.
• Exact Rule Compliance: Continuously matched to published Science Olympiad guidelines.
