Angular interdental toothbrush adapter

thingiverse

I'm making a special adapter for my Auchan brand toothbrush, which I found cheaper at Alcampo supermarkets in Spain. The original brush is angular and pricey, so I've created this simple fix to get the best deal. To use it, just snip off the wire from any straight toothbrush with scissors and slide it into the adapter's hole – it fits snugly with a bit of pressure. When the old brush wears out or breaks, you can simply pull it out and swap in another one. The same handle keeps getting reused, making this DIY solution incredibly cost-effective. By using my adapter, I'm saving a whopping 6€ every month.
