# 3D Printing Guide

Sesame is designed to be printed in **PLA**. Most parts print without supports, but the top cover needs supports in targeted areas. Below is a quick reference for each component:

Note: There are 3 different top cover styles currently available. **Enclosed v91 is recommended** as it's the most modern design with magnetic hat mounts, covered display wires, and multicolor detail support. See [Top Covers](stl/top-covers/) for details on all styles.

> [!NOTE]
> **Battery Upgrade:** The internal frame design has been slightly altered to fit the new recommended battery (Bambu Lab 14500 Li-ion). If you have an older Sesame and want to upgrade to this battery, simply print the new internal frame and install it.

## Recommended Settings

* **Material:** PLA / PLA+
* **Infill:** 8-10%
* **Wall Loops:** 2
* **Infill Pattern:** Honeycomb
