It also works as a coaster for drinks!\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e(If you plan to use it as a coaster, you might want to scale it up to around 130% or so. Check the dimensions in your slicer.)\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eEach ray of light is modeled according to the actual refraction of light traveling through air and glass. Using Snell's Law and the lensmaker's equation, the focal point is accurately positioned and the real behavior of light can be seen in detail.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eThis has been the most difficult design I've modeled so far, and I'm very pleased with the result.

If you want to reduce purge waste, I recommend calibrating your color change with a print like \u003ca target=\"_blank\" href=\"https:\/\/makerworld.com\/en\/models\/112380#profileId-129748\" rel=\"nofollow noopener\"\u003ethis\u003c\/a\u003e. I printed the lens cutaway with a 0.7 flushing multiplier, and I still had a little bit of color contamination. (The profile has been set to 0.8 to improve this.)\u003c\/p\u003e\u003cp\u003eDesign by tyler on MakerWorld (license: BY).\u003c\/p\u003e","brand":"Mymadmanlab","offers":[{"title":"Default Title","offer_id":67412678082864,"sku":null,"price":4.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0987\/0809\/5280\/files\/0_f9442544-60d8-4a6a-b18f-b8a247797154.png?v=1785348313","url":"https:\/\/mymadmanlab.com\/products\/lens-refraction-cutaway","provider":"Mymadmanlab.com","version":"1.0","type":"link"}
