Large tumbler, capable of holding up to 1.2L of fluid, perfect for keeping beverages at the desired temperature for extended periods. The design features a carefully selected motif and custom text, crafted using the "native" xTool Creative Space fonts and figures, ensuring a unique and personalized touch.

In this project, two passes were made during the engraving process, although it might have been achievable with just one. Initial tests revealed either coating residues or "burn marks," leading to the decision to perform an additional pass for a cleaner, more refined result.

Due to the size and design of the tumbler, the chuck of the RA2 rotary attachment was utilized, as the handle interfered when attempting to use the standard roller. This method ensured precise and clean engraving, avoiding any issues caused by the tumbler's handle.
