A simple shot glass. Seven sided and twisted using a helix tool in the CAD software. Mounted on a flared to base to reduce the chance of tipping. The interior has been rounded to ease cleaning. Should hold very close to an ounce of liquid. These are the first part of a slightly larger project.
For 3D printing, a solid infill is recommended to reduce the chance of leaking. The original set saw some outdoor winter use and the guess is that some shrinkage resulted in a slight leak in some of the glasses. A later printing with an infill of 1.0 hasn't had this problem.
