Textured Sleeve for Pura Stainless Water Bottle

thingiverse

I designed this textured grip for the Pura Stainless Steel water bottle. The current silicone grip works well for most people, but individuals with low muscle tone or small hands need a more aggressive texture to securely grasp the bottle. I created this sleeve to address that issue. To ensure durability and ease of cleaning, I printed it using Ninjaflex. Safety Note 1: Although Pura's silicone is food-grade, Ninjaflex is not safe for human consumption. Therefore, if you have a user who tends to chew on the sleeve, use a different material. Additionally, avoid using Ninjaflex for components like straws. Safety Note 2: FDM printing leaves tiny pores where bacteria can grow, making it non-food-safe. For this application, as long as users do not bite or chew on the sleeve, it is safe to use. Print Settings: Printer: Flashforge Dreamer Rafts: No Supports: No Resolution: Medium Infill: 25% Notes: Printed with Ninjaflex at 1000 mm/min. Online speed was 50%, infill speed was 80%. The fan turned on during the second layer, and the bed temperature was set to 40 degrees C, while the extruder reached 230 degrees C. Post-Printing: The sleeve can be washed and used immediately. I must admit that putting it on for the first time required some effort, but it's all part of the process.
