Optician Refraction Bar for 5 Lenses
Description
Refraction bar to use during eye tests. The spot in the handle is for a +1,5dpt lens. (Quicker hyperopia testing.) Refraction bar for 5 lenses with groove and glazing sample for easier tracing and glazing. The glazing sample is just a cutout of the bar so don't worry if you find half a groove on the one side. For glazing I recommend to cut the lenses 1/10 smaller. Note: be aware to change the size of both files the same percentage when you want a bigger or smaller bar. No support needed. Infill can vary depending on how heavy you want it to be in your hands. Made with Tinkercad. I actually use the Anycubic i3 Mega S. Please upload your makes and leave comments! I'm curious how you make and use them :)
