The PrecisionFlex Rotary Combo combines two specialized 3-jaw chuck accessories designed to help secure tumblers during laser engraving. Featuring the PrecisionFlex 81 and PrecisionFlex 95, this convenient bundle accommodates different tumbler opening sizes, making it easier to switch between popular 20 oz and 30 oz drinkware projects.
Manufactured in-house using 3D-printed PLA filament, these accessories feature a flexible three-jaw design that helps grip the inside opening of compatible tumblers while reducing the chance of marking the interior rim.

How the PrecisionFlex Rotary Accessories Work
Engraving tumblers and other cylindrical drinkware requires the workpiece to remain securely positioned as it rotates beneath the laser. An improperly supported tumbler can shift or wobble, affecting engraving alignment.
PrecisionFlex accessories are designed to help support compatible tumbler openings during rotary engraving. Their flexible three-jaw construction provides contact points inside the tumbler opening, while the included bottom stabilizer offers additional support for the workpiece.
The combo provides two nominal opening sizes, allowing users to select the accessory that best matches their tumbler dimensions. Correct positioning, adequate clearance, and proper rotary setup remain essential for accurate engraving.
Choosing Between PrecisionFlex 81 and 95
PrecisionFlex 81:
Designed for tumbler openings measuring approximately 81 mm (3.19"). This size is commonly associated with select 20 oz insulated tumblers, including certain YETI and Polar Camel styles.
PrecisionFlex 95:
Designed for tumbler openings measuring approximately 95 mm (3.74"). This larger option is suited to select 30 oz insulated tumblers and similarly sized drinkware.
Both models offer limited flexibility to accommodate slightly larger openings. Because tumbler designs vary between manufacturers and product generations, measuring the actual opening is the best way to select the appropriate accessory.
Confirm Compatibility Before Ordering
The PrecisionFlex Combo is intended for use with compatible rotary engraving setups. Before ordering, confirm the following:
Your tumbler opening measures approximately 81 mm or 95 mm
The selected accessory fits securely without excessive force
Your existing rotary setup can accommodate the accessory and workpiece
The workpiece can rotate freely without contacting surrounding machine components
Your laser machine has sufficient clearance and focusing range
The accessory's mounting arrangement is compatible with your rotary equipment
These are rotary accessories, not complete motorized rotary attachments. A compatible rotary engraving system is required and is not included. Tumbler capacity, brand, or nominal opening size alone does not guarantee compatibility.
Installation & Safety
Select the PrecisionFlex accessory that matches your tumbler opening and install it according to your compatible rotary setup's instructions. Ensure the accessory is properly seated, the tumbler is supported, and the bottom stabilizer is correctly positioned before engraving.
Verify that the workpiece rotates freely and remains secure throughout its full rotation. Do not force an accessory into an undersized opening. Keep the PLA components away from direct laser exposure and excessive heat, and follow your laser machine's operating and safety procedures.
