You might recall last month that I posted about my 3D-printed spectacles.
Enough people asked me for the files and for details on how to order lenses and mount them into the frames that I figured I’d release everything with instructions - and also redesign the hinges a bit so the temples fold more compact, something I meant to do for some time.

Cool!
Love the ghost in the shell profile pic :)
Great project! I would love to see them on someone. I fortunately don’t need glasses but I might at some point consider printing sunglasses.
Love seeing FreeCAD in use.
It’s getting quite good, and considering what I paid for it, it’s very very good indeed 🙂
Yea I use it for all kinds of things. About to release some smart sensors with enclosures from it, last big thing was: https://nowsci.com/twystlock/
It’s awesome
That’s so cool!
Watch out. Luxotica going to place a hit on you.
Hey, this is really cool! I’m trying to do exactly this but am making my own frames for the first time. Is there some forum where people discuss this? For tips and common pitfalls.
You talked about the registration tab at length. I’m making mine not entirely radially symmetric. Does this mean I don’t need them? Will the lens wabble inside because its PLA?
Does the frame slip more than with other material? Or maybe with a riding bow make it not noticeable.
Was the optician able to bend the temples with heat or was no frame adjustment needed at all?
You’ve made the lens groove in this triangle shape. Is that the standard or will the tracer edger pick up any shape tehre? How’d you decide how deep to make that groove?
How comfortable do you find wearing PLA so far?
how much do lenses cost like this?
It depends on your prescription, the material you choose, coatings and such. The shape of the lenses or the type of beveling have no impact on the price, unless they’re highly curved with a step bevel for instance.
My lenses are standard polycarbonate lenses with a basic scratch-resistant coating. But I have astigmatism and I need progressives, so the lenses come out at $400. And usually I also order a pair for far and near (not progressive) and they’re like $200 per.
That’s the only problem with the registration tabs in my design: it requires notching the bevel of the lenses - meaning you have to work up the courage to bring a file to brand-new lenses you just paid a sizeable portion of your last paycheck for 🙂
The lense cost is usually whatever your health insurance is willing to pay.
If it’s only $40, the lenses cost $40.
