Vitamin bottle cap with day arrow

thingiverse

This cap is designed with safety in mind, featuring a child-resistant mechanism that requires you to push down and twist to open it. However, I haven't verified whether it meets any official standards for child-resistant packaging. The cap comes equipped with an arrow that snaps into one of seven positions, allowing me to track the number of days my daughter takes her vitamins. To ensure a secure seal with the bottle neck, I removed the wax-paper gasket from the original cap and inserted it into this new one. The cap should fit any M53SP400-threaded bottle without issue. It's made up of two distinct pieces: an interior component with threads and an exterior piece featuring knurls. When printing these pieces together, you'll want to enable retraction and use settings that handle overhangs effectively. The print may still sound and feel rough due to the nature of the design. I created this model in Onshape, and it's available for your review [here](https://cad.onshape.com/documents/b8c2b00edc244f3b82b69f32/w/48bc00688a634d8bacf21b89). Feel free to modify the design to suit your needs. Since Onshape lacks a text tool and the ability to import 2D shapes for extrusion, I resorted to printing a sticky label and cutting it to shape using my sister's Silhouette Cameo CNC paper cutter. I've attached an SVG file of a label similar to the one I printed.
