Built by an Enthusiast. Made for Enthusiasts.

Hey, I'm Mo, but most people know me as Elmoh. I'm the person behind Inertia Werks. You probably found your way here from social media, so welcome. I'm glad you're curious enough to want to know more before you buy. That means a lot to me, and honestly, you're exactly the kind of person I make my products for.

Why I Started Inertia Werks

The first part I ever made was a gauge pod bracket that integrated into the vent of my own E46. I made it using a 3D printer I had access to at an internship I was working at. A friend saw it, told me to post it in a local Ontario BMW Facebook group, and I did. To be honest I wasn't expecting anything to come of it beyond a couple sales.

But instead, people started asking if I could design gauge pods for other cars. I got E36, E90, and even some Nissans. Apparently a lot of the drift guys need a place to mount their gauges...who would've thought.

 I didn't take much of that work on at the time. Actually I didn't take on any of that work because I didn't own a printer. I would've been relying on my office Creality Ender 5, which is problematic for 2 reasons: 1. That thing could barely handle PETG, let alone anything engineering-grade. and 2. I was definitely not getting a call back to that job if I spent my entire internship working on my side hustle using company resources. So nothing ever really came of the idea.

The real turning point came 8 months later during my capstone project back in school.

For those curious, I made an Arduino-controlled, electrically powered construction crane, built to 1:60 scale.

The design needed a stepper motor to rotate the boom of the crane. But based on our calculations of torque, we would need a $1000 industrial motor to spin this bad-boy 180 degrees. Good thing we know all about mechanical leverage! So we designed a planetary gear set to rotate the boom without needing an oversized stepper motor, and that gear set needed to be 3D printed because our collective 1 year of machining experience was not QUITE precise enough to machine a gear set. Especially not within the 4 month semester.

In terms of 3D printing, my school had its own little print farm going, but in order for students to use them you were required to submit request forms. Which you can just imagine the wait times for that when every student is cramming to finish their project. (isn't 3D printing supposed to be rapid?)

We  didn't have time to sit around like ducks, so I started paying a classmate to use his personal printer, a Bambu Lab P1S. Just a reminder, the last time I used a 3D printer was 8 months ago and it was an Ender 5. The first part that came off the P1S was so nice that 2 of my groupmates had to pick my jaw up off the floor. 

Now of course, being the "measure once cut twice" person that I am, the design changed and I need a new gear set printed. But that would mean I would pay him again for a reprint, which bothered me because who knows how many times I'm going to mess this up before I get it right. Somewhere in the middle of that annoyance, the idea clicked: "Why don't I just buy a printer myself?"

So I put together what savings I had left from the internship and ordered a P1S Combo at full price rather than wait for a sale. If you haven't realized this yet: speed is very important to me. (There was a flash sale that came out a week after mine shipped :') ).

After setting up the printer in my bedroom (great for white noise when sleeping. Not great for VOCs). I remembered that I still had the gauge pod file sitting and collecting dust on my desktop. And with my new P1S I could print these bad boys without them looking like hot garbage.

And so once my capstone wrapped up that April, I turned my full attention to designing and printing parts I thought other enthusiasts would actually want. More gauge pods, cup holders, and even an intake for the E46.

A few months in, the P1S broke down in the middle of a backlog of orders, literally a week before I was set to leave for Europe to finish my last year of school on a study abroad program. I couldn't wait for the P1S replacement parts to ship (again, speed is very important.) So using all of the money I had made from this venture I picked up an X1C on a whim to keep things moving. That's the printer lineup I still run today.... plus a few new friends.

How Every Part Is Made

Every single part I sell is designed and 3D-printed by me, here in my workspace. I don't outsource production. I don't keep a warehouse of pre-made stock. Each order is made to order, which means what you receive was made specifically for you and inspected by me before shipping.

My design process starts with the car itself. I measure, 3D scan, prototype, test fit, and iterate until the part sits exactly right. I use engineering-grade filaments like ASA and PA6/PA12-CF, chosen specifically because they handle heat, UV exposure, and the real-world conditions of a car without warping or fading. Side note, it stills boggles my mind the number of people that think 3D printing hasn't evolved beyond PLA. I guess that sort of thing just takes time.

A Manufacturing Business, Not a 3D Printing Business

3D printing has come a long way since I first got my hands on one back in 2015, and with the range of engineering-grade filaments available today, it's more capable of real fabrication than ever. But I'll also be the first to admit it isn't a one-size-fits-all solution — other manufacturing methods are still viable, and often better suited to certain applications, especially in motorsport.

That's why I never set out to build a 3D printing business. I knew from the start I'd eventually branch into other manufacturing capabilities. Right now that means outsourcing CNC parts where 3D printing isn't the right tool for the job — but it won't be long before we're producing those in-house too.

No Drill. No Modification. No Compromise.

Every part I design follows one rule: it has to fit without drilling, cutting, or permanently modifying your car. I believe in upgrades that respect your vehicle. Whether you're daily driving or building a show car, you shouldn't have to damage what you love to make it better.

You Think It, We Will Make It

Don't see what you're looking for? That's what my custom part request service is for. If you have an idea — a trim piece, a bracket, a storage solution, anything — reach out. I'll work with you to design and produce it. This is the part of the job I enjoy most: turning someone's idea into something real and tangible that lives in their car every day.
