This project is a collaboration with people living with Cystic Fibrosis (CF) , and one of the daily things that you have to do if you have CF is to take dietary supplements with every meal called Enzymes. These capsules contain, well, Enzymes that work in addition to the ones naturally present in your body to aid digestion. Typically, a person with CF will consume many Enzymes throughout the course of the day with their meals, and the amount varies. Hence a dispenser for the capsules was developed.
Of course, you're totally right - this could be a pill dispenser! It might just require some modification to mean that the sizes are right for an individual type of medicine.
Tl;dr - Enzymes and pills are different things, but this *could* be modified for pills.

As such, we would really like it if you print this, and have some comments on how the mechanism might be improved (or if you make a derivative) that you post a link at the above webspace to the thing you create & upload to Thingiverse.
The dispenser itself is quite simple, and this file will work with a popular Enzyme brand (we can't name the make, or manufacturer), with approximate capsule dimensions of 19mm length x 6mm diameter.
There are 2 files above - Enzyme_Transparent and Enzyme_Opaque. Print both; and as the name suggests, the transparent file is best printed in a clear plastic (so you can see the number of remaining Enzymes, and whether there is one ready to dispense). The opaque file can be printed in any colour you desire.
The parts are assembled as per this Youtube video:
The written instructions are complex, and it's much easier to watch the video to see assembly. The elastic band you'll require is a #32 (type 32) elastic band. If this is called something different in other parts of the world, I can post the dimensions.
Tolerances may vary, depending on the plastic used for printing, and the print settings / environmental conditions. For information, approximately 25 of these have been printed reliably on the following machine and settings:
MakerBot Replicator (Dual)
V 7.0 firmware
25% infill, 3x shells
50ÃÂÃÂºC Bed, covered in 3M Blue Tape
(sticks like poop to a blanket that way).
Finally, this is a WIP. The development of this continues, and it should be noted that there are still issues to solve! Not least, how this is filled reliably and speedily- and what sort of casing this mechanism might fit into. Perhaps a CNC wooden or Aluminium case, made in a Fab Lab? The sky is the limit.
