Decathlon water flask protection lid

thingiverse

I had an issue with my water flasks, their mouth ends were always getting stuck in the dirt and then I always had to clean it before drinking. I designed this simple protector that just gets put on the mouth end to protect it. The protector also has a small 4mm hole for attaching an accessory cord to prevent losing the protector during hikes or climbs. I printed it with PETG because of those hot summer days, but maybe PLA would work just as well. No supports needed. Infill is not important, the wall is 1.6mm thick so it will create 4 walls, without any infill. At the end of printing I used a hot air gun to remove all thin lines created during combing. To minimize combing within the inside, play with the rotation of the object to find that sweet spot.
