LEGO Tank Tracks and Caterpillar 3D Models to Print

This collection gathers 3D models of tank and caterpillar tracks, from single track links to full hulls and chassis that use them. Most files are aimed at LEGO Technic builders and at anyone printing tracked vehicles on a 3D printer. It helps you find a track unit first, then the body or mechanism that goes with it. 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.

Informazioni sulla categoria

«LEGO Tank Tracks and Caterpillar 3D Models to Print»

The range splits into a few groups. There are individual track links and replacement treads, wider or narrower variants of the same link, complete tank hulls and bases that take a track unit, scale tank kits, and treads for bulldozers and other construction machines. Robotic and RC builds form another group, where tracks are part of a driving chassis rather than a static model.

Before printing, open the author's page and read the notes there. Check the stated scale and overall dimensions, how many parts make up one link and how they join, whether the author mentions support requirements, and which material and slicer settings were used. Photos of actual prints show how the links sit together and how much cleanup the pin or hinge areas need.

If a search returns little, try other words for the same idea: track link, tread, caterpillar track, tank track, or the machine type such as bulldozer or crawler. Related topics worth browsing are RC tank chassis, robotics platforms, and construction vehicles. Narrowing by scale, by track width, or by the pin style used to connect links usually cuts the list faster than adding more keywords.

FAQ

Domande frequenti

What is the difference between a track link and a full track model?
A single link is one repeating piece you print many times and join into a loop, while a full track model is a complete assembly or a hull that already includes the running gear. Links give you control over length and width; full models save assembly time.
How do I know how many links I need for a track loop?
The author's page usually states the link count for a given scale or wheelbase. If it does not, measure the path around the wheels and divide it by the pitch of one link, then print a few extra links.
Which material works for printed tracks?
It depends on how the links join and how much load they carry. Stiff filaments hold shape well for static models, while more flexible ones can help where links bend around small wheels. The author's listed material is the safest starting point.
Can printed tracks be combined with building-set parts?
Many models in this collection are drawn around standard pins and axles, so they are meant to work alongside building-set components. Check the connection points shown on the model page before printing a large batch of links.
