Thermoscan lens filter container

So you have a wonderful Braun Thermoscan to measure temperature of your children and you are reusing lens filters (on a personal basis) to not waste money buying hundreds of filters. Ok, mee to :) But where to store lens filters, when not in position on the thermometer?
Here is a perfect solution that is working great for me! Put the lens filter into this container, that was shaped to fit exactly the filter, and close the cap! No more lens filter crushed (they are so easy to crush...) and no dirty on them!
If you have more children to measure temperature just print more containers! They are free ;)
You can then put a small label on them, writing the name of the child.

Please, if you print it put a picture in the "made" section of this thing! Just that as a small remuneration...
