What about creating your own glass ?
Size, shape , colour , logo all of them depends on you.
It sounds great . Maybe you can rival starbucks 's coffee glasses :D
So how can I do this ?
'CATIA PROGRAM ' (Computer Aided Desing )
Actually , this program is used often in Aerospace , automobile and other department. You can design your product in 2D & 3D model.
Lets see my glass :D
This glass has real size which is around plastic glass size.
First step : Draw semi shape of glass which is in your mind . Enter the sizes . Go to exit workbench and create cylinder.
Second step : Draw shape where you hold and decide colour of your glass .
Finally we created own degign .
I hope enjoy :))) Have a creative day :)
