Print your own custom-fit sunglasses in classic wayfarer style with this DIY Wayfarers kit.
These modular, 3D-printable sunglasses are designed for makers and DIY enthusiasts who want durable, stylish eyewear in five sizes: Baby, Small, Medium, Large, and XL. Each frame is printed with grooves that secure the lens mid-print—no screws or snaps needed.
Unique Features:
Integrated lens lock: The frame print pauses at a specified layer so you can drop in your cut lens. Resume the print to permanently lock it in.
Interchangeable sizing: All arms and frames share the same hinge geometry. Mix and match arms and frames from separate build plates for a personalized fit.
Cut-to-fit lens system: Use the included lens-cutting templates and standard scissors to trim a shaded Face Shield Replacement (available on Amazon).
Simple arm connection: Slide a piece of 1.75mm filament or 14-gauge wire through the hinge holes to attach the arms. Apply a small dab of glue in one hinge to hold it in place. Snip any excess material.
Assembly Instructions:
Print the arms of your choice along with a matching lens cutting template (if you are mixing arms and frame sizes, make sure you print the right template for your frame)
Cut the shaded lens using the template and some good scissors or a hobby knife.
Start printing the frame and the print will pause at the lens insertion layer.
Insert the trimmed lens into the paused print and resume to lock it in.
Connect arms to the frame using a piece of 1.75mm filament or 14-gauge wire as the hinge pin.
A - Arm length measurement; from the back of the frame to approx the center of the ear hook F - Frame width measruement; the inside distance between the two arms
The Process:
Printed legs with the corresponding lens template A c-clamp and a good pair of scissors work really well here.
Lens and a piece of face shield in the clamp
The cut lens edges dont have to be perfect, but as close to the template as possible is good. Slightly smaller than the template is better than bigger so it fits in the frame and the frame will hide the rough edges
The printer will pause at this point
Push in the lens ensure they are below the edges and not stuck up at all or the toolhead will hit it On my P1 series, I turned down the aux fan a bit at this point as it was moving my one lense that was a bit loose
There may be a bit of stringing due to the overhang trying to print on the lense A flat edge wood carving knife made quick work of them. Any sharp blade should clean these up without much issue
Push your filament or 14 ga wire into the hinge to act as the hinge pin. You can apply a small drop of glue into the end hole so the pin does not slide out later.
The diamond is an optional aesthetic, if you dont like it, just set both print colors the same.
