I recently started using a steel water bottle, with 39mm neck. The bottle is about 17 to 18oz, but it is a smooth bottle with no loop or handle. After a quick look online, I noticed that I could buy a cheap handle for quite a bit. So, after a little thought and a nearly successful version 01, I created the Crafty Clip 2. Printed on my Resin printer and just thick enough to make it sturdy, but flexible, I made something that works. Printed at a 35 degree angle, a habit from using FDMs to print the clip for best flex and strength, I cured it and snapped it onto the bottle. The bottle is the standard cola style 17oz steel thermos bottle, so it should be a universal fit.
