CH340G STL: Cases for USB-to-TTL and Arduino Boards

This collection gathers STL files for CH340G-related hardware: enclosures for USB-to-TTL adapters, cases for Arduino and ESP8266 boards, and snap-fit boxes. It helps you find a housing that matches a specific board layout. Check the model page for dimensions and assembly notes before 3D printing.

«CH340G STL: Cases for USB-to-TTL and Arduino Boards»

The models range from simple two-part shells for USB-to-TTL sticks to multi-piece cases for Arduino Nano, Uno, and ESP8266 NodeMCU boards. Some designs are snap-fit and need no screws, while others use screws or sliding lids. Board-specific cases often include cutouts for USB ports, reset buttons, and pin headers.

Before printing, compare the board dimensions and port positions with the model's stated measurements. Check how many parts the case has, whether supports are needed, and what material and layer height the author suggests. Photos of actual prints can show how well the openings and tolerances work.

To narrow results, try synonyms like USB-to-serial adapter, TTL converter, or UART module. Related searches include CH340, CH341, Arduino Nano case, and NodeMCU enclosure. Adding board names or port types to the query can surface more specific designs.

FAQ

常见问题

What is a CH340G?
The CH340G is a USB-to-serial chip used on many inexpensive development boards and adapter modules. It lets a computer communicate with microcontrollers over USB.
Will a case for one CH340G board fit another?
Not always. Board dimensions, USB connector type, and pin header layout vary between manufacturers. Compare the model's measurements with your specific board before printing.
Do these cases need supports?
It depends on the design. Some are printed in two halves that lie flat, while others have overhangs that may require supports. The author's page usually notes this.
How do I find a case for my Arduino Nano with CH340G?
Search for the board name plus 'case' or 'enclosure', and include the CH340G keyword if you want to match that chip version. Check the model page for the exact board revision and port layout.
