# 🖨️ 3D printing

<div style="text-align: justify;">

This section provides the 3D printable components used in the MICKY robot. All parts were designed to support the mechanical structure and facilitate integration with electronic components, while maintaining low cost and ease of fabrication.

## Before Printing

> We assume you have basic experience with consumer-level 3D printers (K1 Max, Ender 3, etc.). This means you know how to properly 3D print STL files with PLA filaments and are familiar with reorienting parts, adding supports, adjusting infill, and modifying print speed to achieve your desired balance of material strength, efficiency, and model detail quality.

<!-- - For more detailed information, you can check out the 3D printing instructions for [Lekiwi](https://github.com/SIGRobotics-UIUC/LeKiwi/blob/main/3DPrinting.md) and [SO101 Arm](https://github.com/TheRobotStudio/SO-ARM100#printing-the-parts). -->
- All the 3D printed parts shown in the images of MICKY were printed using a **Creality K1 Max with PLA Speed Premium Orange filament**.
- Drying PLA is recommended for humid environments at 45°C for 8 hours before printing.

This component secures the wheel motors to the robot structure, ensuring proper alignment and stability during operation. It is designed to withstand mechanical loads generated by the locomotion system while maintaining ease of installation and replacement. An aluminum profile is placed between each pair of motor mount assemblies to reinforce the structure and improve overall rigidity.

This component holds the batteries in place, providing structural support and protection during operation. The design ensures stability and easy access for installation and replacement.

```{note}
The robot design provides space for four batteries, with two dedicated exclusively to powering the locomotion system, while the remaining two are intended for use with an external computer, if needed.

### Cost Considerations

* **Own printer** (Recommended): Everything can be printed on consumer 3D printers like the Creality K1 Max (~$899.00 USD).
* **Filament cost**: Approximately $38–55 USD for the required PLA filament.
