3D Printable Oil Funnels and STL Funnel Models

This collection gathers 3D models for oil funnels, from threaded versions that attach to a filler neck to wide workshop funnels for bottles and canisters. It is useful when you need a specific diameter, thread or spout length that a store-bought funnel does not cover, and you would rather print it on your own 3D printer. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

«3D Printable Oil Funnels and STL Funnel Models»

The models fall into a few recognizable groups. Threaded funnels are shaped around a particular filler opening and often include a vent channel, while workshop funnels are simply wide-mouthed cones for pouring into bottles and canisters. Parametric files let you set the diameter, spout and wall thickness yourself, and a smaller group adds lids, trays or separate parts that keep the funnel tidy between uses.

When choosing a file, read the author's page for the thread size and pitch, the outer diameter, the spout length and the number of separate parts. Check whether the model is meant to be printed in one piece or assembled, whether supports are needed, and which material and layer height the author lists. Photos of real prints show how the surface and the thread came out, which matters more here than in decorative models.

If the results are too narrow, try related terms such as threaded funnel, filler neck funnel, transmission or coolant funnel, or a diameter and thread description instead of a brand. Searching for a parametric funnel, a funnel with a lid, or a funnel for a specific container size usually brings up different files. You can also browse broader utility and workshop categories and then filter by the shape you need.

FAQ

常见问题

What thread sizes do 3D-printed oil funnels use?
Authors usually state the thread diameter and pitch on the model page, often matching a common filler neck or a bottle opening. Measure the opening you want to fit and compare it with the dimensions given before printing.
Which material works for a funnel that contacts hot oil?
Most people print funnels in a common filament and use them for short pours at moderate temperatures. The model page often names the material and settings the author used, so start there and consider how hot the liquid will be.
Do these funnels need supports?
Many are designed as a single cone that prints without supports, but threaded versions and models with handles or vents may need them. The print orientation and support requirement are usually described in the file notes or visible in the photos.
Can I change the size of a funnel model?
Parametric files are made for that: you adjust the diameter, spout and wall thickness in the source file and export a new mesh. On a fixed STL you can scale it, but the thread and wall thickness change with it, so check the fit afterwards.
