3D Models for Ender 3 Cases and L-Size Parts

This collection gathers STL files for Ender 3 electronics cases, L-size containers, adapters and small scale parts. It helps when you need a printable enclosure, a holder, or a part sized in liters or marked L-3. Check each model page for the author's notes before you start 3D printing. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

How this collection is put together

Polyzon assembles this collection from search results on the connected platforms. Repeats and models without a preview are removed, weak matches go to the end, and the rest keeps the search order. Models belong to their authors — check the terms on each model's page.

About the category

«3D Models for Ender 3 Cases and L-Size Parts»

Electronics cases and mounts form one group, often made for Ender 3 frames and MKS Gen L boards. They differ by board size, port cutouts, mounting points and whether the design includes room for buck converters or cable routing. Other entries cover liter-sized watering cans, wall protectors and tank plugs, where the main variables are volume, thread type and wall thickness.

Scale models and small mechanical parts appear as another group, including simplified military vehicles and artillery pieces with an L-3 designation. These are usually split into several parts, so check the scale, part count and assembly order. For any model, look at the author's listed material, layer height, supports and photos of real prints to judge how it will behave on your 3D printer.

To narrow the search, try synonyms and related terms: enclosure, housing, case, mount, bracket, adapter, organizer, holder, watering can, tank plug, scale model, and the liter or size labels that appear in titles. Combine a printer or board name with the part type, or search by volume and thread standard when the item is a container or fitting. If results are too broad, add a material, a printer model, or a specific size range.

FAQ

Frequently asked questions

What does L-3 mean in these 3D model titles?
It can stand for different things depending on the model, such as a size label, a vehicle marking, or part of a board name. Check the model page and its category to see how the author uses it.
How do I choose between different Ender 3 electronics cases?
Compare the board dimensions, port positions, mounting method, and whether the design leaves space for extra modules. The author's photos and notes usually show the layout.
What should I check before printing a liter-sized container or plug?
Confirm the volume, thread size, wall thickness and material listed by the author. A test print of the thread or fitting can help before printing the full part.
Can these models be scaled up or down?
Scaling changes wall thickness and fit, especially for threads, enclosures and assembled parts. Check the author's notes and adjust only if the design allows it.
