7-day circular pill box with rotating shutter, plus locking mechanism. Includes days of the week (single letter abbreviations) and secret storage compartment behind locking mechanism. Compact (60 mm dia, 30 mm high) - good for travel. 

Note: Dividers in top piece require supports in centre. (If you are using Prusa slicer then supports should be included in 3mf file.)

To assemble: fit shutter in track on bottom piece. Fit top piece, line up dividers and locking mechanism cut-out, then screw in bolt (note: bolt will not feel tight - this is to prevent over-tightening). Finally, insert locking mechanism.
