Thermos Lid Replacement

thingiverse

version 1: Kids FooGo thermos lid cracked from a thermos bought back in 2010. I designed a replacement part that functions as the original. It seals the straw and the pressure hole and stays latched. Might not fit the new thermos designs.I printed several version to make the latch work properly. I printed it top side down. The top has a 6 degree slope so you can set your CAM software properly to make it flat. Version 2: So I had to make a version 2. The fit of the original was acceptable but not as good as I would have liked. So I messed with the latch and made it tighter and slightly stronger. I just had to tweak it and really like the new fit. version 3: So I found that some of the straws leak when in use and then found my air hole block was in the wrong location. It has been fixed in version 3 now and all seems well with 2 different straws. Final Update: So I have all the kinks worked out. I did find that I had to use an XActo knife and trim a little bit of the edge off of the latch part on the lid. It prevents the button from coming all the way out when the lid is closed. It is just a little bit off the end of the triangle that locks into the receiver of the button latching the lid closed. Update: October 17, 2016 I just uploaded the button that corresponds to these FooGo lids. It is at http://www.thingiverse.com/thing:1833663 on thingiverse. Print Settings Printer Brand: SeeMeCNC Printer: Rostock MAX Rafts: No Supports: Yes Resolution: 0.4mm nozzle, 0.1mm layer Infill: 25% Notes: Put supports under the latch lip and the back of the lid when printed upside down. When printed right side up, you need a ton more support and I didnt get good results. I used simplify3D for slicing/CAM. How I Designed This Fusion 360
