Bottlecap Cover - Bottlecap Stopper

This reusable stopper will keep insects and sand outside your bottle, while keeping most of the drink inside. It works with opened bottlecap bottles - and can be printed in PLA!

Stoppers come off with a satysfying pop, while the loop saves them from getting lost in sand/grass.

You can print them in various colors to mark the bottles during a party/camping/barbecue.
 

changelog:

• V1 - cover, isnt really watertight but prints well in PLA
• V2 - stopper - springy inner stopper is intended for something like PETG or TPU, but even printed in PLA is almost watertight - few drops can escape if the bottle is turned over
• V3 - stopper with sturdier connection to the loop. The loop and stopper are also a little easier to press-fit on bottle
• no-loop version added
• V3.1 - Minor cosmetic changes. The loop is even easier to press-fit on bottle
