Lid Handle (no support)

thingiverse

ATTENTION!!!! ABS plastic is highly resistant to heat, able to withstand temperatures up to 100 degrees without sustaining damage. However, it's recommended to avoid contact with food when handling this material as it may release toxic substances when heated. To prevent potential harm, I strongly advise against using a printed washer and instead opt for screwing the handle directly or selecting a more heat-resistant washer that doesn't emit hazardous chemicals. I designed a lid handle model that operates without any support, mounted securely on top of the table at an optimal 50-degree angle. This angle ensures the best possible quality when printing parts made from ABS plastic. At steeper angles, print quality will deteriorate and may necessitate additional support, as I've personally experienced. The ideal design features two walls, but three is even better. For a strong and stable structure, fill at least 10% of the material, with an optimal filling percentage of 25%. To achieve this, use a grid pattern for the filling, or experiment with different percentages to find your preferred result. A 4mm screw hole provides ample space for securing the handle in place. In my final design iteration, I refined the transitions between parts to create a smoother surface that makes it easier to grasp. When printing on glass, the surface can take on a glossy finish depending on the adhesive used. This sleek appearance will undoubtedly look impressive.
