Rubbermaid Cap Topper
thingiverse
We have several old Rubbermaid water bottles (20 oz and 30oz) with vacuum seal tops. Unfortunately, the snap tops are now becoming brittle and breaking. I decided to design a replacement so we could extend the life of the reusable bottle a bit longer. Please check out the pictures to see if they might work for you. I designed it in Tinkercad and am definitely a beginner so feel free to refine the design. This is version 2.0 with a beveled edge instead of a rough 90 degree edge. I like to include the .gcode file, so beginners using PLA on an Ender 3 Pro (or similar) can just print it based on my exact settings.
