Lunyee 3018 Pro Ultra — Dust Collection System (Adapter + Sliding Mount + TPU Nozzle)

Model Overview & Print Notes

Summary Dust Collection System for Lunyee 3018 Pro Ultra CNC A complete 3D-printed dust collection setup that I designed for my Lunyee 3018 Pro Ultra. The system connects a standard household vacuum cleaner to the CNC, keeping the workspace clean and protecting your lungs from MDF, wood, and PCB dust. What's included: 1. Vacuum Hose Adapter Adapts a thick standard vacuum hose to a thin electrical cable trunking (the kind you find in any hardware store). The thin tube is much easier to route close to the spindle without obstructing the work area. 2. Dovetail Sliding Mount Bolts onto the spindle holder. Features a dovetail rail that allows the nozzle assembly to slide up and down, so the suction stays close to the cutter at any Z height. 3. Flexible TPU Nozzle Printed in TPU (flexible filament) for safety — if the spinning bit accidentally contacts the nozzle, it bends instead of shattering. No flying plastic shards near your face. Print settings: Material: PLA or PETG for adapter and mount, TPU 95A for the nozzle Layer height: 0.2 mm Infill: 30–40% Walls: 3 perimeters Supports: only on the dovetail mount (minimal) Hardware needed: 2× M4 bolts and nuts for the dovetail mount Vacuum cleaner (I used a 1600W Samsung with variable speed) Standard PVC electrical cable trunking as the suction tube Notes: The TPU nozzle works great for general milling, but for PCB engraving I'm currently designing dedicated low-profile nozzles — they will be uploaded as a separate remix once tested. Designed in Fusion 360. STL and STEP files are included so you can modify the design to fit other CNC machines with similar spindle mounts. If you print this, please share a Make — I'd love to see it in action. Feedback and remix suggestions are welcome. Happy milling!
