Lately I need to protect my toothbrush from house lizards / house geckos. I did not want to buy a toothbrush holder with a cover so I looked around my house to find materials that I could use to make one. In the end, I made one using two PET bottles and the lid of a small container.
I started off with two PET bottles (only one bottle is shown in the photo below), a small container and a scissors.
Cut each bottle into 2 parts. I only need the bottom part. Then cut a hole in the middle of the lid of the small container.
Result: a toothbrush holder with a cover. The lid of the small container holds the toothbrush in place inside the bottom part of the 1st bottle. The bottom part of the 2nd bottle acts as the cover.
