Replacement lid for Fresk thermos bottle

The original lid broke when I dropped the bottle... This replacement screw-on cap omits the rubber carrying loop of the original, but otherwise gets pretty close. Make sure to reuse the original cap's sealing ring with the new cap!
The cap has a quite thick centre section to still make it insulate somewhat well.

The Fresk thermos bottles have a 54 mm outer diameter thread with a 4 mm pitch. Pretty nice bottles, worth the effort to create a replacement part!
