We 3D Print Custom Parts — Here's What That Actually Looks Like

Most people know us for custom laser engraving — slate coasters, cutting boards, crystals. But there's a whole other side to what we do at 3Blades Maker Lab: custom part design and 3D printing.

We're talking functional, real-world parts. Mechanical assemblies, organizers, replacement parts, jigs, brackets — if you can describe it, we can probably design and print it.

Instead of trying to explain it, let us show you two recent projects from start to finish.

Project 1: Custom Tri-Arm Bearing Housing

A customer came to us with a mechanical part they needed — a precision housing with an internal tri-arm assembly. No off-the-shelf solution existed.

Step 1: Design

We started with the customer's rough measurements and created full technical drawings with precise dimensions.

Step 2: 3D Model

From the drawings, we built a complete 3D CAD model — every bolt hole, every curve, every tolerance accounted for.

Step 3: Production

The part was printed on our BambuLab H2D in engineering-grade filament. We sent the customer photos and video updates throughout the print — they could see their part taking shape in real time.

Step 4: Delivered

The finished multi-piece assembly, ready to go.

Project 2: Letter & Number Stamp Organizer

Not every project is a complex mechanical part. Sometimes it's about solving a simple, everyday problem.

A customer had a set of metal letter and number stamps — the kind used for stamping serial numbers and markings. They were all rattling around in a cardboard box with handwritten labels. Finding the right stamp meant digging through the pile every time.

Step 1: The Problem

Step 2: Design

We designed a custom organizer tray with individually sized and labeled slots for every letter, number, and symbol in the set.

Step 3: Production

Printed in durable black PETG on the BambuLab. Again, we sent progress photos throughout — our customers are always surprised at the level of involvement we provide. Sending photos and videos of the progress throughout the day keeps you in the loop and makes the whole process feel collaborative, not transactional.

Step 4: Delivered

Every stamp has its place. No more digging.

What Kind of Projects Do We Take On?

Pretty much anything that can be designed in CAD and 3D printed:

• Custom part design — from a sketch, a photo, or just a conversation
• Replacement parts — broken part with no replacement available? We'll reverse-engineer it
• Prototyping — test your idea before committing to expensive tooling
• Organization solutions — custom trays, holders, mounts, and organizers
• Jigs and fixtures — production aids, alignment tools, assembly fixtures

We charge a flat $90/hour, and most projects run between 2 and 6 hours. We always give you a free estimate before we start, so there are no surprises.
