That is superb. Sadly my eyes degrade faster than the frames wear out!
I see you are on the John Lennon specials which makes it a bit easier to model. I haven't worn circular specs since college (~1990) My current Tesco specials only have lens frame from the nasal bridge clips, over the top to about 5mm below the temple joints.
Just a thought but you might like to investigate using spring steel for the arms and PLA just for the frames. You could create a jig for joining and heat the ends of the arms up with a brazing torch (kitchen supplies) and sink them into a suitable cylinder close to the temple joint. If you go all in you can make the straight part of the arm rigid and the over ear part flexible with careful heating and cooling and whacking with a hammer!
Now, that metal work will be comfortable but might be a bit chilly. What about PLA tips over ear instead of steel?
Anyway, great job. I'm very impressed.
I haven't worn anything but small round glasses since I discovered why they're just better: small and round lenses can be positioned very close to the eyes, which provides a very large field of vision. And they're less fragile and prone to breaking if you hit your head on something or snag the end pieces on clothing.
And of course, frames are easier to make. I haven't bought frames in 30 years. I make my own.
Nah. Those PLA glasses are in fact a copy of a frames I made of silver nicket - and wound spring steel wires for the ear hooks - and having worn them all day for 3 days now, I actually enjoy the feel of PLA better. And it's so much lighter! It really does make a difference.
And of course, if I break them, I can print another set of temples in minutes. If I don't like the feel, I can lengthen them or shorten them in FreeCAD and again, within minutes, I have new ones. No more faffing around with the heat gun or anything.
I really dig the disposableness of it all 🙂
Good skills Sir! Advice noted and I will re-evaluate how I do specs.
Thank you.
