This is a 7 day pill/vitamin dispenser with seperate files to print a magnetic box(** 6, 10mmx2mm magnets/box**) to attach boxes together or a box without magnetic cut-outs. It also have seperate files for a AM, Noon and Pm lids. It also has a ball bearing( 4mm) and spring( an old lighter spring works great 3mm- 3.5mm). The spring and ball bearing will make the lid stop on each day flawlessly. The printable set screw needs a 2.5mm allen wrench to tighten the spring. Use PLA, bed , 55 - 60 degrees, nozzle 205 - 210. Print the set screw seperate at a finer and slower speed. a Drop of oil on the set screw works great.
