Fitting entering the socket
Measure the real outside diameter at several positions and check for taper, seams, ribs or out-of-round geometry.
Editable dust-port adapter template
Make a measured 35 mm to 50 mm dust-port reducer
This starter joins a 35 mm socket end to a 50 mm spigot through a tapered open passage. Measure both real workshop fittings, choose the engagement lengths and wall, then print the separate end-fit trials before committing to the complete adapter.
A measurement-led starting point for an awkward workshop connection—not a claim about nominal hose sizes, universal dust-port standards, airflow or vacuum performance.
What to measure first
The starter dimensions are there to make the controls understandable. Replace them with evidence from the real part, space and print setup.
Port receiving the spigot
Measure the real inside diameter and the usable depth before deciding the spigot diameter and engagement length.
Available straight engagement
Record how much of each connection can engage without striking shoulders, blast gates, clamps or internal obstructions.
Adapter envelope and support
Check the 34 mm transition space, surrounding equipment and how the finished adapter will be supported independently of its printed fit.

From measurement to printable part
The generator keeps the important decisions visible and carries one parameter set through geometry, inspection, calibration and export.
Measure both real fittings
Do not rely on the advertised hose or port size. Record the actual mating diameters, shapes, shoulders and usable engagement depths.
Choose which side is socket and spigot
The socket grows around a measured male fitting; the spigot shrinks to enter a measured female port. Keep those clearance directions explicit.
Review the passage and envelope
Adjust transition length and wall thickness, then inspect the internal shoulder, outside envelope and intended print orientation.
Print both end-fit experiments
Use the tighter, selected and looser trials for each real fitting with the same material and profile planned for the adapter.
Inspect and prototype the connection
Export the checked printable mesh, then test the supported assembly for fit and application behaviour without inferring a rating from the STL.
Print notes
- Print every circular-end trial before the complete adapter; the two ends are separate fit experiments.
- Inspect the complete internal passage, shoulders and transition in the slicer, especially if the narrower end is placed on the bed.
- Keep the final adapter supported so hose weight, vibration or equipment movement is not carried only by a printed friction fit.
- Dust and static hazards depend on the complete extraction system, materials and equipment; this template does not assess them.
Know the limits
- The part has no pressure, vacuum, airflow, temperature, chemical, static-control, pull-off, strength or load rating.
- Nominal 35 mm and 50 mm labels do not establish the dimensions or profile of a real workshop port.
- A fit coupon establishes only the tested dimensional interface on the recorded print setup; it does not prove sealing or safe extraction performance.
Common questions
Answers specific to this starter and the measurements it exposes.
What are the finished starting diameters?
With 0.25 mm radial clearance, the 35 mm socket starts at a 35.50 mm bore and the 50 mm spigot starts at a 49.50 mm outside diameter. Measure and trial both real fittings before using those values.
Can I swap the socket and spigot ends?
Yes. The Adapter Builder supports measured circular end styles independently. Recheck the engagement, transition and print orientation after changing an end style.
Will this fit standard dust-extraction hose?
There is no universal fit claim. Advertised sizes can describe different surfaces, and real ports may be tapered, ribbed or out of round. Measure the exact parts and print both fit trials.
Does the reducer preserve airflow?
The generator creates an open tapered passage, but it does not calculate pressure loss, collection velocity, turbulence or system performance. Those require separate application assessment and testing.
