This was designed for use during rehabilitation of a stroke patient who had reduced mobility of the arm and wrist along with pronounced pronation of the forearm.  The mug has two adaptations:

  • The mug only needs to be tipped 45 degrees to drink all of the liquid.
  • The handle shape makes it easier to hold with pronation of the forearm.

Printing and Usage Tips:

  • Print with 0.15mm layer height and 6 perimeters.  This ensures that it is water tight and adds a decent amount of mass to the feel when held, but it does result in a fairly long print time (~17 hours on my Prusa Mini+).
  • The model is left-handed.  Mirror the model in your slicer if you need a right-handed cup.
  • Use PETG to allow the cup to be put in the top rack of a dishwasher.  Only use PLA for cold beverages (PLA should be hand-washed only).
  • As with any 3D printed container for food or beverages, it is a good idea to disinfect it periodically with a diluted bleach solution.

I hope this helps others in their recovery.
