🦋 20OZ BUTTERFLY HANDLE TUMBLER SLEEVE BLANK – DIGITAL 3D PRINT FILE 🦋

Create your own personalised tumbler sleeves with this 20 oz Butterfly Handle Tumbler Sleeve Blank.

This design combines a straight-sided protective tumbler sleeve with a decorative butterfly-shaped handle, giving you a ready-made base that you can print as supplied or customise with your own designs, names, graphics and themes.

Perfect for makers wanting a blank base without having to build the tumbler fit and handle geometry from scratch.

📏 DESIGNED TO FIT

The sleeve has been designed around a straight 20 oz skinny tumbler measuring approximately:

Tumbler diameter: 74 mm
Tumbler height: 205 mm including lid

The design allows approximately 35 mm of the tumbler to remain exposed above the sleeve.

The model includes approximately 0.8 mm clearance per side around the tumbler for fitting.

Sleeve Dimensions

Internal bore: approx. 75.6 mm
Main sleeve outside diameter: approx. 82 mm
Sleeve height: 174 mm

Approximate Overall Butterfly Model Size

92.1 mm W × 165.4 mm D × 174 mm H

The larger overall depth is due to the decorative butterfly handle extending from the sleeve.

🦋 DESIGN FEATURES

• Decorative butterfly handle
• Straight-wall 20 oz tumbler sleeve
• Approx. 3.2 mm main wall thickness
• Approx. 4 mm base thickness
• 14 mm push-out hole in the base to help remove the tumbler
• Rounded rim and lower edges
• Ready to print or customise further

The fit geometry was created specifically around the 74 mm tumbler diameter rather than simply scaling a generic cup holder.

This is a digital 3D model, so you will need access to a 3D printer and suitable slicing software.

Actual fit can vary slightly depending on:

The exact dimensions of your tumbler

I recommend checking the dimensions of your tumbler before printing the full model.
