Double Gear 3D Models: STL Files for Printing

This collection gathers double gear 3D models, from small fidget rings and spinners to helical assemblies, pumps and shafts. It is useful when you want a moving part for 3D printing rather than a static figurine. Each listing leads to the author's page, where the files and notes live. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

Come è composta questa raccolta

Polyzon compone questa raccolta a partire dai risultati di ricerca dei siti collegati. I doppioni e i modelli senza anteprima vengono rimossi, le corrispondenze deboli finiscono in fondo e il resto mantiene l’ordine dei risultati. I modelli appartengono ai rispettivi autori: verifica le condizioni sulla pagina di ciascun modello.

«Double Gear 3D Models: STL Files for Printing»

The models fall into a few groups. Fidget-oriented pieces pair two gears so the outer ring or body turns against the inner one. Mechanical versions, such as helical and planetary sets, gear pumps and gearboxes, are built to transmit motion or move fluid. Simpler entries cover single shafts, tooth-count variants and parametric generators that let you set the geometry yourself.

When choosing, look at the tooth count, module and shaft diameter first, because those decide whether two parts mesh at all. Check how many separate pieces the model contains, how they are joined, and whether the author notes supports or a particular orientation. Read the material and slicer settings listed on the page, and look at photos of finished prints to judge clearances and surface finish.

To narrow the search, try related wording: helical gear, spur gear, planetary set, worm gear, rack and pinion, gear generator, gearbox, fidget spinner. Adding a use case, such as pump, keyring or crank, usually cuts the list faster than adding adjectives. If you need a specific ratio, search by tooth numbers or by the shaft size you plan to use.

FAQ

Domande frequenti

Do double gear models need supports?
It depends on the orientation the author chose. Overhangs on gear teeth and bores often print cleanly when the part lies flat, while vertical shafts may need support. The model page usually states whether supports were used.
What do module and tooth count mean when picking a gear?
Module describes tooth size, and tooth count sets the diameter and the ratio between two gears. Two gears only mesh correctly when their module matches, so compare those values before printing a pair.
Can a double gear fidget be printed without extra hardware?
Many designs are printed as one piece with a built-in axle, while others expect a bearing or a pin. Check the parts list and the assembly notes on the author's page to see what the model assumes.
How do I scale a gear model without ruining the fit?
Scaling changes tooth size and clearances together, so a resized pair may no longer mesh. If you need a different size, look for a parametric generator or a version with the tooth count and bore you want.
