I had new progressive lenses made, but the old ones are still fine and don’t have a scratch. They’re just a bit weak at near distance, but otherwise perfectly serviceable.
So I made new frames for them because I don’t like to throw away things that work.
All assembled, the frames weigh 3.5 grams, and 14 grams with the lenses mounted.
This was printed with a Prusa Mk4 and regular PLA at 0.15 mm layer height. The hinges use simple 10x1 pins - and I worked my magic to print the holes horizontally to the final dimension with interference fit, so no reaming or drilling is necessary. These glasses are straight out of the printer with zero rework.
I think they look pretty good as they are. If anybody notices they’re 3D-printed, I’ll say I’m gunning for that particular style 🙂
The front of the frames prints in 11 minutes and both temples in 12 minutes. I could break and make a new pair every day for the rest of my life and it would still be faster and cheaper than going to Specsavers only once.
You can smooth PETG with Methylene Chloride, but I would not suggest handling things without proper training and knowledge first
Yeah. Even with acetone you want to be mindful. Nasty stuff and not to be played with lightly.
But interesting application if you can do it safely.
Yes boss! And PLA can be smoothed using clorophorm. Another solution not to handle without safety training
Try explaining that purchase.
It’s for smoothing out something I’m making. So it’ll look and act the way I want.
And the lotion? No officer, no lotion. Where would the lotion go?
