Summary

I haven't uploaded anything in a while so I figured I would post one of my old favorites. Some time ago I wanted to try my hand at making a nice little 3D printed coffee cup. Now, one thing to remember is that PLA is not actually food safe. So instead this cup uses a stainless steel insert. The actual 3D print part of it acts as thermos with a small air gap between the steel part and the plastic part. I also prefer having a nice big handle. And this style of handle is not only easy to print but comfortable. Layer adhesion is really important for the handle but this version has stood up for over half a year with no issues.

For the inserts you can purchase them on amazon. Im sure there are other places you could get it cheaper but I cant really garuntee they will fit.

Once again you can find the original design on my Onshape profile.
