A handle to screw on standard glass jars to reuse it as a mug for cold drinks.Find more about Project RE_ on Instructables : http://www.instructables.com/id/Project-RE-by-Samuel-Bernier/and onhttp://project-re.blogspot.ca/Find a standard 4 tread glass jar that has a 2.5'' opening. Print the handle. The lip should be facing the table so almost no support will be needed. Clip, screw and enjoy!Sincerely,Samp.s I would definitely NOT put the pug in a microwave or anything significantly hot in it. Their thill isn't any food safe/ microwave certified material for low cost 3D printing, but it is on it's way. It's a bit like using tupperware from the 70's. Be careful.
