Where Engineering
Meets the Lane.

This is where ideas are born, tested, refined, and proven. Not in a corporate lab — in a home shop in Hawthorn Woods, Illinois.

Before there was a Bambu P2S, there was wood. Hand-cut, carefully assembled, functionally sound — but time-consuming and not something a high-volume pro shop would ever consider. Those early wood jigs worked well enough to prove the concept, but they also proved something else: the concept deserved better materials.

In late February 2026, a Bambu P2S arrived. The first simple designs were in TinkerCAD — simple, functional, exploratory, but then I needed something more powerful. Enter Fusion 360, and with it, a level of precision that changed everything. My first 3D printed jig was made with PLA and fully intended to be a simple proof of concept. When it not only performed well but was handling the rigors of multiple ball drillings I knew I was onto something.

The background was there — 27 years as a Systems Engineer, before that, a mechanic and machine operator who understood materials, tolerances, and the unforgiving reality of real-world performance. This wasn't a hobbyist experiment. This was engineering discipline applied to a field that had been waiting for it.

PLA gave way to PETG-CF, ASA, PA6-CF. Simple clamps evolved into vacuum-assisted ball retention systems. A hand span tool became a patent-pending precision measuring instrument. And a conversation with a respected local pro shop ownerbecame a mentorship that continues to shape every product in the catalog. Every item I sell was born out of a real-world necessity for something better, easier, and more affordable.

Rolling Down The Lane™ exists because the bowling industry deserves better and more affordable tools — and FDM manufacturing is finally capable of delivering them.

The Wood Jig Era

Hand-crafted wooden ball drilling jigs — functional, proven, but labor-intensive. Too time-consuming for volume production, but enough to validate the core concept. The seed was planted.

Origin
Feb 2026

The Bambu P2S Arrives

A Bambu P2S printer enters the garage. First prints in TinkerCAD — simple and exploratory. The transition from wood to FDM begins immediately.

Milestone
Mar 2026

Fusion 360 & The Engineering Bug

Progression to Fusion 360 unlocks parametric design. The first PLA jig performs flawlessly. PETG-CF replaces PLA. The engineering discipline that defined a 27-year career now drives product development full time.

Turning Point

The Thumb Slug
That Changes Everything.

Conventional thumb slugs are limited by the tools used to make them. A drill press can only do so much. But Fusion 360 and a precision FDM printer have no such limitations — which means we can engineer relief cuts, custom ovals, and exact pitch geometries that are simply impossible any other way.

My wife has a bone spur on her thumb. Traditional slugs were never going to work for her. A custom FDM slug with a precisely engineered relief cut solved the problem completely. If it works for her, it can work for thousands of bowlers dealing with the same issue.

We're launching a limited beta program soon. Be among the first to experience what custom FDM thumb fitting actually feels like.
