Why T-Slot Aluminum?

T-slot aluminum is often referred to as "Legos for Adults" because of its incredible versatility.

It's a fantastic option to any project that requires lightweight + strong material. It's a great alternative to steel because it's lighter and it doesn't require welding so this means it can be easily assembled and disassembled.

The "T" slot design on all four sides gives you the freedom to easily add more rails or accessories without any cutting involved. Components such as nuts, bolts, and connectors can be easily inserted into the slots with no special tools. Despite its lightweight nature, it delivers impressive strength allowing you to bear considerable weight.

People have used T-slot aluminum in a wide range of places, from labs, warehouses, and pickup trucks to vans and schools. Basically, whenever you need a durable and customizable solution without the need for welding, T-slot aluminum is the way to go!

Design Your T-Slot Aluminum Project!


Is this a downloadable app?
No! It all works on the browser. It works on your phone as well as your computer!

Is it free?
Yes the app is 100% free.

Can I save my design?
Yes! You can save your design in your account.

Can I share my design?
Yes! You'll have a unique URL for every design you save which you can send to anyone! They can then see or clone the design. They cannot edit your design. You can also delete it whenever you'd like.

What materials do you support?
Crafty currently have 1000 parts across
aluminum 8020, steel, wood, HVAC and PVC! Let us know if we're missing a part.

Where did the idea for this app come from?
I spent a year building an off grid farm and knew nothing about construction / plumbing / electrical work…
I saw that most people had to go the hardware store multiple times and many times they weren’t able to finish their work that day because the vendor didn’t have the part. So I thought if you can design your project beforehand, it will allow us to check for compatibility while you’re designing and then be able to send you all the parts! Much easier!

Can I connect PVC to wood, t-slot / aluminum 8020?
Yes. There are transition parts that allow you to connect PVC to wood or wood to aluminum 8020. If there is interest, we will start adding parts like motors and electrical components as well.

The idea for Crafty is to be a place where you can design your entire project with all of its components so when you want to get to building, all you need to do is order!

Do you have everything in stock?
No, not everything. We currently have about half of the parts and our goal is to little by little add more.
For the parts we don't have, we will give you a link for the provider that you can buy it from. Hopefully as the app gets more traction, we will start to carry more and more items so we can ship you everything in one set.

How do you deal with long and heavy parts (like 2x4s)?
When you have parts longer than 36" or of a certain kind (like lumber beyond a certain WxH), we just give you the dimension / exact length for you to go buy that at your local store. It doesn't make much sense to ship a 2x4 :)

Are you going to add more parts?
Yes. This current set of parts that you see on the app is our initial set. We just finished this version in late April 2023 so we’re listening to the feedback we get and will evolve the app to be the best that it can be for all of you!

Why not just use CAD?
You can! If you have all the parts downloaded already and are an expert in CAD software. Also, I would hope that your CAD software gives you a clean output of all the parts / their exact measurements.
What CAD software won't do is allow you to share the design online and allow others to see your design and specs.
