My modification adds holes for LEDs and a trench to run wires in, creating safety glasses that combine with a head lamp to provide light when working in dark places. Frame Modifications The modifications made to the frames were simple: holes were added to both top corners between the edge of the frame and the hinges to hold LEDs. Two holes were also added to the bridge, and a narrow trench was created to hide wires that run in-between the LEDs. Printing I found the best way to print the frame is shown in the photo. Printing the frame this way gives you the maximum detail on the trench that runs in between the holes. You also get to print without supports. This file has a lot of small details, so I recommend printing it at a lower layer height. The frame needs to be sturdy but doesn't have to be solid since it is only going to be resting on your nose. I recommend printing around 35% infill. Post Printing To assemble the frame, the arm needs to fit in the groove and the pin needs to slide in from the top. When I printed my models neither of these worked. I had to file the groove larger and drill out the holes so the pin would fit. Arm Modifications The only thing needed to be done to the arm of the glasses was to add two holes, used to mount the battery case to the arm of the glasses, but only if you are using BatteryCase.stl or Old_Battery_Clip.stl. Printing When printing the arms, I found the easiest way to get the part to adhere to the build platform was to lower the model in the slicing software just past the platform and then slice it. Unless you can print at a 45˚ angle, supports will be necessary to print the bent end of the arm. Again, there are small details on these files so a small layer height should be used; I used 0.2. Post Printing After printing, there were some rough edges where the support was touching the arm. That part of the arm would be resting on the ear, so I sanded it down after the support was broken off. The holes that the battery case would attach to were also drilled out. Battery Case Design The battery cases were designed in Google Sketchup then re-exported using Meshlabs to fix all the errors that Sketchup is known for. There are two versions of the Battery case: BatteryCase.stl, made to fit in the holes in the modified arm, and BatteryCase_Glue.stl, designed to be simply glued to the side using super glue or your choice adhesive. Printing These models don't have to be printed at an extremely low resolution because there is not much detail. Support is needed to print BatteryCase.stl because of the pegs that stick out of the bottom. Post Printing To prepare the battery case, two bolts and two nuts are needed. The bolts are used to push against the batteries and make the electrical connection while the nuts are used to tighten against the wire and hold it in place. To finish the post printing, the battery case can be glued or snapped onto the arm. Old Battery Clip Modifications This battery clip was modified by adding two holes, used to mount the battery case to the arm of the glasses, but only if you are using BatteryCase.stl or Old_Battery_Clip.stl. Printing I printed them in PLA so I don't know if they would hold up better if they were printed in ABS. I included the file in case someone wanted to try. Wiring Parts Needed 5mm LEDs, large gauge solid wire Wiring The LEDs are inserted into the holes and the wires go from the battery case and are soldered to the first LED. The wires are then extended to the other three LEDs one at a time putting them in parallel. Final Thoughts Files The files for this project are not perfect, and you may find simple errors in the meshes or scaling. Feel free to share them with me so I can fix them for later versions. Uses These glasses were designed for the main purpose of illuminating your work surface when working in the dark. While constructing them, I thought of many other things that could be done with them like: Party glasses (if you use blinking RGB LEDs) Anti-camera glasses (if you use infrared LEDs) And even better yet a no hands cat toy (if you use lasers) Enjoy Printing Print Settings Printer: Kossel Rafts: No Supports: Yes Resolution: 0.2 Infill: 35% Notes: Read summary for more details
