LDO Delta Flyer 3D Printer Kit – By Rolohaun

Experience the thrill of delta kinematics with this captivating DIY build project!

From the brilliant mind of Rolohaun—creator of the beloved Rook printer—comes the Delta Flyer, an open-source delta 3D printer that’s as satisfying to build as it is impressive to watch in action. Whether you’re building your first delta or adding another engineering marvel to your workshop, the Delta Flyer delivers an exceptional building experience backed by community-trusted LDO Motors quality.

Why Delta Flyer?

For the Builder: This isn’t just another kit—it’s a masterclass in delta mechanics. The Delta Flyer features a sleek, modern design with premium linear rails and robust 2020 aluminium extrusions. Every component has been thoughtfully selected to create a smooth, rewarding build that teaches you the elegant simplicity of parallel arm kinematics. First-time delta builders will love the approachable design and excellent community support, whilst experienced makers will appreciate the quality engineering and performance potential.

Compact But Mighty: Don’t let the 115mm diameter build area fool you—this space-saving powerhouse is perfect for prototypes, miniatures, technical parts, and test prints. The vertical delta design means it takes up minimal desk space whilst delivering impressive print speeds and that mesmerising delta motion we all love to watch!

Technical Specifications:

• Build Volume: 115mm (diameter) × 115mm (height) – circular build plate
• Frame: 2020 aluminium extrusions for rigidity with minimal weight
• Motion System: Precision linear rails on all three axes for silky-smooth movement
• Arms: Lightweight carbon fibre (CF) arms for reduced moving mass and lightning-fast acceleration
• Motors: Standard NEMA 17 stepper motors (easy to source, replace, and upgrade)
• Electronics: Compatible with BigTreeTech Manta E3EZ and BTT DZ01 boards
• Firmware: Klipper – unlock advanced features, input shaping, and impressive print speeds
• Enclosure: Fully enclosable design for printing ABS, ASA, and other temperature-sensitive materials
• Design: Open-source by Rolohaun, with extensive community documentation and support

What Makes It Special:

Linear Rails: Smooth, precise motion on all axes—feel the quality in every movement

Carbon Fibre Arms: Maximum rigidity with minimal inertia for rapid direction changes

Klipper Ready: Advanced motion control, pressure advance, and input shaping out of the box

Community-Driven: Backed by Rolohaun’s reputation and an active, helpful community of builders

Compact Footprint: Perfect for crowded workshops or as a dedicated small-parts production machine

Open Source: Full access to design files, modifications, and community improvements

The Build Experience:

The Delta Flyer offers that perfect sweet spot of challenge and satisfaction. You’ll learn about delta calibration, belt tensioning, and precision assembly—all whilst creating a beautiful, functional printer. Detailed documentation and a supportive community mean you’re never building alone.

Important Notes:

This is a DIY kit – Some assembly required! (That’s the fun part!)

Not included: Hotend and printed parts must be sourced separately. This allows you to choose your preferred hotend and print the parts in your material/colour of choice!

Recommended for: Makers with basic 3D printer knowledge and a passion for building. First-time delta builders welcome—this is an excellent entry point!

Perfect For:

• Makers wanting to explore delta kinematics
• Experienced builders seeking a fun weekend project
• Anyone who needs a compact, fast printer for small parts
• 3D printing enthusiasts supporting open-source design
• Those who find joy in the building process itself
