Spinbrush head cover, scale for any toothbrush.

thingiverse

This is a cap I designed to fit a spinbrush electric toothbrush. You can easily scale it up or down to suit any type of toothbrush. The inside diameter is 12.7mm, but you'll need to adjust the size if your toothbrush has a different width. To ensure a tight fit, reduce the dimensions by 0.2mm compared to the width of your toothbrush. For example, if your toothbrush measures 12mm in width, try scaling down the print by 7% for a snugger fit. This will give you an inside diameter of approximately 11.8mm. I'd love to see your creations and hear your feedback!
