Printed original model and it was just too loose and let my Owala slip open. So I went into Tinkercad and fixed up the model. I made 3 variants just in case, but the +1mm version worked absolutely perfect for me. Uploading the others to save others trouble if that's too much or too little!

Files Included:

• + 0.66 mm

•  +1 mm (Worked perfect for me)

• + 1.66 mm to this one

Here is how I printed mine:

Print Settings:

• Material: Inland Olive Green High Speed PLA+

• Support: Tree Supports . You will need supports for the part!

• Print Orientation: Have it on its side, that is the strongest orientation. Screenshot provided!

• Layer Height: 0.2mm worked well for me

• Infill: 0%

• Walls: 6
