Sanding Dust Collection Station —HOZO NeoSander

Designed alongside the HOZO NeoSander. Modular benchtop dust capture downdraft table for resin, PLA, and wood sanding.

Sanding 3D prints kicks up the kind of dust you don't want in your lungs — and a paper towel under the workpiece doesn't cut it. This benchtop station catches falling sanding dust through a replaceable filter sandwich, then routes the air through whatever you've got: your shop vac, or a $10 12V fan if you don't. Drop your NeoSander on the upper mesh, sand directly over the tray, and the dust gets captured instead of breathed. Drop the whole station inside a desktop paint booth and the booth's filter catches what stays airborne — the station handles the falling dust, the booth handles the drift.

FEATURES

• One box, three connection options — print the adapter that matches your setup: 32mm, 35mm, or 38mm shop vac, or a 12V radial fan for a standalone unit
• Paint booth friendly — fits inside most desktop paint booths (CO-Z and similar). The radial fan exhaust elbow redirects airflow toward the booth's intake so the two systems work together: station catches falling dust, booth catches airborne fines
• Industry-standard nail dust filter paper (19×24cm) — ~$10 for 200 sheets on Amazon, replace when loaded
• Filter sandwich design — paper filter pressed between two printed mesh trays, no glue or tape
• Standalone fan mode — no shop vac? Print the fan adapter and run a ~$10 variable-speed 12V centrifugal blower (AC wall adapter included)
• Single .3mf project — one download, multiple plates, pick what you print
• Fully parametric — open the SCAD file in OpenSCAD or the MakerWorld customizer to tune filter size, hose diameter, fan position, and more

⚠️ HARDWARE CALLOUT (Radial Fan variant only)

⚠️ Radial fan variant requires:

• 1× KUNRISE 12V variable-speed centrifugal blower, 97×33mm body, 65mm inlet. AC wall adapter and inline speed controller included. ~$10 on Amazon: https://www.amazon.com/dp/B0FRF71NX8
• Also sold under Martians, WDERAIR, and other brand names — same physical fan with different stickers. If sourcing a different brand, confirm 97×33mm body and 100mm diagonal mounting hole spacing before ordering.
• 2× M4×40mm machine screws + 2× M4 nuts (any hardware store, ~$2)

PRINT SETTINGS

Recommended material: PETG-CF body with PLA support interface PETG-CF gives you the rigidity and dust resistance the station needs; PLA support interface peels clean off PETG without fusing.

Required plates (print all three)

Pick ONE adapter plate

Layer height: 0.2mm (0.4mm nozzle) or 0.28mm (0.6mm nozzle) Wall count: 4 Infill: 15% gyroid for box, 100% for mesh trays Supports: Tree (slim), build plate only — slicer auto-flags where needed

⚠️ Hose adapter is OPTIONAL. It's a 90° elbow for routing your hose around obstacles (like a paint booth back wall). Print if you need it; skip if your hose has clearance.

HARDWARE / WHAT YOU NEED

PAINT BOOTH INTEGRATION

Drop the station inside a desktop paint booth (CO-Z and similar models are confirmed compatible) and the two systems complement each other:

• The station's filter paper catches the falling sanding dust as it drops through the mesh.
• The booth's intake filter pulls any airborne fines (the particles that don't fall straight down) into the booth's filter behind the station.

Between them, you cover both the dust that drops and the dust that drifts.

For the radial fan variant, the included exhaust elbow redirects the fan's lateral airflow back toward the booth's intake so the two airflow systems work in the same direction instead of fighting each other.

Customizer tip: if the elbow's exit is too long for your booth's depth, shorten elbow_exit_length and elbow_sweep_radius under "Radial Fan Adjustments." Defaults are tuned for a CO-Z booth.

See the listing demo video and animation for airflow visualization during actual sanding.

TIPS & TRICKS

• Measure your shop vac hose cuff OD with calipers before printing. Brands quote "1.25-inch" or "1.5-inch" but real OD varies 0.5–1mm between brands. The customizer lets you enter the exact diameter to match.
• Hose adapter prints in two pieces — the slot adapter and a 90° elbow. The elbow is optional but lets you route hoses around obstacles (great for paint booth setups).
• Fan mode users: the included exhaust elbow redirects the fan's lateral airflow. Aim it back into a paint booth filter or just away from your work area.
• Filter loaded? When airflow drops or the filter paper turns gray, swap it. Lift the upper mesh, replace the paper, drop the mesh back on.
• Sanding wet? Don't. The paper filter clogs fast with damp material. This is for dry sanding only.

CUSTOMIZER PARAMETERS

This model is fully parametric. Open the SCAD file in OpenSCAD or use MakerWorld's parametric customizer to tune:

• Filter Setup — paper size, filter overlap, paper vs boxed filter
• Box Sizing — plenum depth
• Hose Connection — type (slip-over, insert-into-socket, or radial fan), diameter, engagement length
• Radial Fan Adjustments — fan distance from box, elbow sweep radius, exit length (tune for your paint booth depth)

Default parameters match my test build. Adjust to fit your filter paper supply or workspace constraints.

SHARE YOUR CONFIGURATION

If you customize this for a different hose size, filter paper, or workspace setup, share your print profile in the comments or as a remix. I'll feature standout configurations in the listing as community variants. CPAP hose users, Festool quirks, oversized paint booth setups — let's build a library.
