Start with both exact model numbers. If no proven file exists, measure the two connections. Hark Tech prints passive vacuum and dust-extraction adapters to order and posts them across the UK.
Example dimensions only. The ordered file must match the real connections.
These community designs cover the most useful routes: measured hose reducers, workshop tool connections and attachment cross-fits. Open a model to check the maker's fit notes and available print options.
MEASURED END A → MEASURED END B
A broad parametric family for unusual round hose and tool connections. Match the file dimensions to both rigid ends.
WD3 VAC → SELECTED TOOLS
Separate maker-described connections for named tools. Check the exact model list before ordering.
35 MM → 50 MM
Three connection variants for the maker's named Bosch interfaces.
D27 / D36 → STRAIGHT
A simple straight interface in the maker's two named hose sizes.
SHARK VAC → DYSON TOOL
Reuse a compatible Dyson attachment on the maker's described Shark interface.
35 MM VAC → DRILLING CUP
A passive vacuum cup for the maker's described 35 mm shop-vac connection.
Compatibility is creator-described. Brand names identify the intended interface. Hark Tech has not hardware-tested these examples, so compare your exact model and connection before ordering.
STL, STEP and 3MF files are priced from their actual geometry.
Upload and price the fileThen check the independent maker's named machines and fitting notes.
Search the full catalogueFour readings and clear photos give an unusual connection the best start.
Use the measurement guideA small adapter can start at the £6 print minimum. With current Royal Mail Tracked 48 delivery, that is £11.55 delivered in the UK. The estimator shows the actual file price before checkout.
Common moulded reducers and mass-market Dyson converters can cost less than Hark Tech’s tracked delivered minimum. Those are better bought as standard parts. The useful Hark Tech lane is an exact or hard-to-find interface where the geometry is proven.
Use digital callipers if possible. Measure the rigid connection, not a flexible hose wall. Repeat each reading at two angles in case the part is oval.
Send model numbers and measurementsNo. They are independent aftermarket community designs and are not endorsed by the named manufacturers. Brand and model names identify the intended interface only.
No. Compatibility is described by the independent creator unless the page explicitly records a Hark Tech hardware fit test. Compare the original maker’s notes and dimensions with your exact equipment.
Send both exact model numbers, clear photos and the four diameter readings. Hark Tech can review whether a suitable licensed file already exists and whether separate design work is practical. A print quote does not include design work unless stated.
No electrical battery adapters, pressure-system parts, machine guards, certified filtration components or other safety-critical interfaces are offered through this page.
