3D Models for HY300 Gear and 300-Series Parts

This collection gathers 3D printing models that surface around 300-series numbers, HY300 hardware and a few parts that share the same digits for other reasons. It covers projector add-ons, scale vehicles and small workshop fittings. It helps when a part code is the only thing you have to start from. 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 Models for HY300 Gear and 300-Series Parts»

Projector accessories form one group: caps, brackets and holders shaped around a particular housing. Vehicle entries split between scale models of motorcycles and cars and functional parts such as fenders, hose guides and glass-lift components. A third group is generic hardware — pulleys, flanges and profile brackets — where the number in the title refers to a size rather than to a machine.

On the author's model page, check the stated dimensions and scale first, because a part number alone rarely fixes the size. Look at how many separate pieces the model has, whether supports are needed, and which material and settings the author lists. Photos of real prints show how surfaces, thin walls and small holes came out.

If results are thin, try the bare number, the full part code, or the object type on its own — projector mount, mudguard, scale model. Related terms like lens cap, servo mount or profile bracket often return more entries. Adding a scale or a diameter narrows a broad number down.

FAQ

Questions fréquentes

What does a 300-series number mean in these titles?
It can be a model code, a size in millimetres or a machine designation. The title alone does not tell you which, so read the model page for the author's description.
Can I scale a model to fit a different part?
Scaling changes wall thickness and hole diameters along with the outer size. Compare the dimensions the author lists with your own measurement before printing the full part.
Do these models need supports?
It depends on the geometry. The author's page usually states whether supports are needed and how the part is oriented on the build plate.
How do I find a part when I only know the number?
Search the number together with the object type, then try synonyms for the part name. Broad terms such as bracket, holder or adapter often bring up more entries.
