Types of Custom Parts We Print

From one-off repairs to small production runs — if it fits in a 256 × 256 × 256 mm build volume, we can print it.

Brackets & Mounts

Wall mounts, shelf brackets, camera mounts, sensor holders — any rigid structural support.

Housings & Enclosures

Electronics enclosures, Raspberry Pi cases, control boxes, and protective covers.

Adapters & Connectors

Pipe adapters, hose fittings, interface plates, and transition pieces between standards.

Gears & Pulleys

Spur gears, timing pulleys, idler wheels — suited for light-duty and prototype mechanisms.

Spacers & Standoffs

Precision spacers, PCB standoffs, alignment shims, and bushing sleeves.

Clips & Fasteners

Cable clips, panel fasteners, snap fits, retaining clips, and spring-loaded catches.

Covers & Caps

End caps, port covers, dust shields, button caps, and protective plates.

Knobs & Handles

Equipment knobs, tool handles, adjustment wheels, lever grips, and ergonomic handles.

Jigs & Fixtures

Assembly jigs, drill guides, soldering helpers, and alignment fixtures for workshop use.

Custom Replacement Parts

Broken appliance knob? Missing clip? Discontinued part? Upload a model or send measurements.

Industries & Applications

Custom 3D printed parts solve problems across every field — anywhere a specific component doesn't exist off-the-shelf.

Small Business Prototyping

Test product concepts, create functional prototypes, and iterate designs without the cost of injection mold tooling. Ideal for startups and inventors bringing a new product to market.

Home Repair & DIY

Replace broken appliance parts, create custom organizers, print furniture hardware, or fabricate that one-off bracket that doesn't exist at the hardware store.

Automotive & Motorsport

Dashboard mounts, gauge pods, wire routing clips, custom brackets, vent adapters, and interior trim pieces. ABS and PETG handle under-hood temperatures.

Electronics & IoT

Project enclosures for Raspberry Pi, Arduino, and ESP32. Sensor housings, PCB mounts, cable management, and custom bezels for displays and buttons.

Lab & Workshop Equipment

Test tube holders, equipment mounts, tool organizers, calibration fixtures, and bespoke lab accessories that commercial suppliers don't offer.

Agriculture & Outdoors

Irrigation adapters, seed spacers, tool mounts, greenhouse clips, and weather-resistant PETG parts for outdoor installations.

Material Selection Guide

Choosing the right filament is the most important decision for a functional part. Here's what each material does best.

PLA

Strength
Moderate
Heat
~55°C
Flexibility
Rigid, brittle

Best for: Prototypes, form checks, visual models

Easiest to print. Not suitable for sustained heat or heavy mechanical stress.

PETG

Strength
High
Heat
~75°C
Flexibility
Semi-rigid

Best for: Functional parts, brackets, enclosures

Best all-round engineering material. Good layer adhesion and chemical resistance.

ABS

Strength
High
Heat
~100°C
Flexibility
Semi-rigid, impact-resistant

Best for: Under-hood automotive, high-temp housings

Excellent heat resistance. Can be acetone-smoothed for a polished finish.

TPU

Strength
Moderate
Heat
~60°C
Flexibility
Flexible, rubber-like

Best for: Gaskets, vibration mounts, bumpers, grips

Shore 95A hardness. Stretches and compresses without breaking.

Tolerances & Specifications

FDM 3D printing is excellent for functional parts — but it has characteristics you should design for. Here's what to expect.

Dimensional Accuracy

Typical tolerance is ±0.2 mm on the XY plane and±0.1 mm per layer on the Z axis. Parts that need to interface with other components should include 0.2–0.3 mm clearance in the design. We can achieve tighter tolerances with slower print speeds and post-processing on request.

Layer Lines

FDM parts have visible layer lines. Standard layer height is0.20 mm (good balance of speed and quality). Fine layers at 0.08 mm dramatically reduce visibility but increase print time 2–3×. For truly smooth surfaces, ABS parts can be acetone vapor-smoothed as a post-processing step.

Print Orientation Effects

FDM parts are anisotropic — stronger along the X/Y plane than in the Z direction where layer adhesion is the weak point. For load-bearing parts, we orient the model so the primary stress direction aligns with the layer plane. Let us know which direction your part will be loaded and we'll optimize accordingly.

Post-Processing Options

Beyond the raw print, we offer sanding and finishing for smoother surfaces, acetone smoothing for ABS parts, heat-set insert installation for threaded connections, and spray-paint priming. Post-processing is quoted separately via thecustom request form.

Custom Parts — Frequently Asked Questions

What CAD formats can I upload for custom parts?

We accept STL, 3MF, and OBJ files. If your part is designed in Fusion 360, SolidWorks, or FreeCAD, export it as STL or 3MF before uploading. 3MF is preferred because it preserves units and color data.

How tight are your dimensional tolerances?

FDM printing achieves approximately ±0.2 mm on the XY plane and ±0.1 mm per layer on the Z axis. For press-fit or snap-fit features, we recommend designing with 0.2–0.3 mm clearance. Critical dimensions can be tested with a small batch before committing to a full order.

Which material should I use for a load-bearing part?

PETG offers the best balance of strength, layer adhesion, and ease of printing for most structural parts. For heat exposure above 60°C, use ABS. For parts that need flexibility or vibration damping, TPU is the right choice. We can advise on the best material for your specific application.

Can you print threads and screw holes?

Yes, but with caveats. FDM-printed threads work well for M6 and larger. For smaller threads, we recommend printing a pilot hole and using a tap to cut threads after printing, or designing for heat-set inserts, which provide much stronger and more repeatable connections.

How do I order a replacement part for something that broke?

If you have a 3D model file, upload it directly. If not, you can send us photos and measurements through the custom request form. For common household items, we can often find or create a model. Reverse engineering from measurements is available for a design fee.

What's the cost for a typical custom part?

Most small functional parts (brackets, clips, knobs) cost between $5–$25 depending on size, material, and infill. Upload your file for an instant quote — pricing is calculated from actual sliced dimensions, not estimates.
