EZ Miter Gutter Template

Our main challenge in this project was achieving the right fit between the template and the gutters. Working on the CAD model of the template, we found that while the design looked great in the software, the 3D printed prototypes were not fitting the gutters perfectly.

It was largely because getting the dimensionally accurate profile of the gutter was rather difficult. Due to its small thickness, the gutter was easy to deform, however, the template needed to work every time.

Moreover, we need to make the template a 3D printable product so it could be launched quickly.

This project is a great example of how a product can be launched quickly and inexpensively by substituting traditional manufacturing techniques, like injection molding with 3D printing. Because we designed the product to be 3D printable for mass production, DJ was able to start selling it within a couple of weeks and without major upfront investments.

Using 3D printing for manufacturing his product as opposed to injection molding, DJ saved tens of thousands of dollars and started to get revenue in a matter of a few weeks since the day he came up with the idea.

That allowed him to direct some funds into growing his company and developing and launching new 3D printed products.

Jobsite tools are tested by the worst conditions, not the best

A gutter template is used on a ladder, in wind, by someone wearing gloves. It has to register consistently on real material that is never perfectly straight, survive being dropped, and be faster than the method the installer already trusts. Anything that requires care to use will be abandoned.

What we designed

We studied how miters are actually cut in the field, then designed positive registration features that locate on the gutter profile itself so the cut repeats without measuring. Prototypes were tested by installers, and the final design was detailed for durable, low-cost production in materials that tolerate weather and rough handling.

Frequently asked questions

Do you test tools with real users?

Yes. Field testing with trade professionals is part of the process, not an afterthought.

Can you help protect the design?

We prepare patent drawings and work alongside your attorney on utility and design filings.

What production methods suit tools like this?

Injection molding, sheet metal forming or extrusion, chosen against volume and durability targets.
