I made these Glasses in TinkerCAD… Unfortunately I am in the hospital psych ward for a little bit so i cant test print.

that being said I have my Laptop. and my Mentor for CAD design Andrew is a believer in experimenting with different designs. and when he has spare time works to constantly better his CAD skills. Almost like the people who just see how fast they can make a design then make it again from scratch 5 more times to get quicker and learn the software. honestly hes a good mentor for this type of thing!
