Ender 3 V3 SE 5015 Fan Duct and Shroud STL Models

This collection gathers STL files for the Ender 3 V3 SE that centre on 5015 blower fans: ducts, shrouds, dual-fan mods, filament guides and small mounts. The parts are aimed at people who want to change how air moves around the hotend and the printed part. Each entry links to the author's page, where the geometry and print settings are described. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

«Ender 3 V3 SE 5015 Fan Duct and Shroud STL Models»

Single 5015 ducts replace the stock part-cooling fan with one blower and reshape the outlet around the nozzle, while dual 5015 shrouds hold two blowers and split the airflow. Adapters are narrower in scope: they mate a 5015 to a particular hotend or sensor mount. Filament guides and gantry braces belong to the same family of small printed parts, but they address feed and rigidity rather than cooling.

Before printing, read the model page for the outlet size, the screw spacing and the number of separate parts, since a duct that clips onto one hotend may not line up with another. Check whether the author lists supports, the material and the settings used, and look at photos of real prints to judge wall thickness and the fit around the fan. Parts that sit close to the nozzle are usually printed in a heat-tolerant filament, while guides and mounts further away can be made in a general-purpose one.

Search terms can be widened with synonyms: blower fan, radial fan, fan duct, shroud, fan mod and cooling upgrade all describe similar parts. Related topics include part cooling, hotend adapters, filament guides, camera mounts and bed shims. Adding the printer name or the hotend model to the query narrows the results.

FAQ

Perguntas frequentes

What is a 5015 fan in this context?
A 5015 blower is a radial fan of roughly 50 by 15 mm that pushes air out of a side outlet instead of straight through. Ducts are shaped to direct that airflow to the hotend or to the printed part.
Do these ducts replace the stock cooling fan?
Many of them do, and some keep the original fan for the hotend while adding a blower for part cooling. The author's page usually shows how the fan is mounted and wired.
Which filament should be used for a duct near the hotend?
Authors often state a material on the model page. Parts close to the nozzle are commonly printed in ABS, ASA or PC, while guides and mounts further away are often made in PLA.
Can a 5015 duct be used with a different hotend?
It depends on the outlet shape and the mounting holes. Compare the dimensions given on the model page with your own hotend before printing.
