A little about what I do
I’m Justin. I run 3D Print BC, work on websites through JR Media Group, and build software for the jobs I keep doing by hand.
From a browser window to the print bed.
Software & experiments
A voice assistant, tools for running a print business, and a calculator for pricing jobs. Some have public code; others are still in development.
A local-first AI command centre with voice interaction, connected tools, and personal automation.
An operational workspace for customers, quoting, tasks and printing workflows. JROS source is private; Project Titan is the earlier public project.
An open-source pricing utility for time, materials and practical job estimates.
My businesses
FDM printing in Richmond. Replacement parts, prototypes and small batches, shipped across Canada.
02Websites, branding and custom tools for businesses that need something of their own.
03My software project for business email signatures and automated replies.
Business owner. Maker.
Usually working on something.
Away from the homepage
A replacement part that’s hard to find. A website that needs fixing. A repetitive job that could use a better tool. Those are the kinds of projects that keep me interested.
This site brings my businesses and side projects together. It’s a place to see what I’m building and get in touch if there’s something you’d like to work on.
