The Door Handler

Human: (For some reason Thingiverse is not displaying all the pictures I uploaded, although they can be seen in edit mode. However, you should still be able to access them.)\r\n\r\nI created this project after becoming frustrated with having to perform break-dance when trying to open doors without touching the handle. This was just a quick fix for the problem and there are many ways it could be improved, but my focus was on creating a simple and easy-to-print tool that wouldn't take up too much time. Maybe it's a silly idea, but I think it's better than using your sleeves or elbows. There is a small carving to add rubber bands, which provide better friction and protect the door when pushing it with the tool. However, currently the bands tend to peel off when stashing or removing the handler in and out of the jeans watch pocket. There is a hole for attachment, but this might only make sense with a retracting line. I plan to create another version tomorrow with more rounded edges to protect the rubber band from cutting and a deeper carving for the bands so they don't slide off. Right now you may need to work on the edges of the finished print and smooth them out with sandpaper. Some other ideas include possibly making a rubber band retractable lid for the front part that touches the handle or maybe a magnet belt holder. The thumb rest might also be better if it's lower. Another idea was to reduce the touching area by adding a triangle edge inside the front u-shaped part. I left some things for you to work on if you'd like.\r\n\r\n=== Notes on Cleaning PLA\r\n\r\nPLA is not the best material to clean because the printed surface is not even and although it can be rinsed with boiled water for a few seconds without a problem, you can't cover it. The PLA will soften in a short time due to heat, so dishwashers are also not an option. Ethanol is possible, but I read that it tends to make PLA brittle over time. Maybe coating the tool with some protective layer like spray paint could help.\r\n\r\n=== Important Note about Stability and Print Settings\r\n\r\nI used 15% filling with the wonderful Gyroid pattern for the print and it seems quite stable, although I DID NOT TRY OUT THE FORCE IT TAKES TO BREAK IT. You might want to experiment with a higher filling density. The print nozzle was 0.4mm and layer height was 0.15mm. With these settings, it uses up around 5 meters of PLA and takes about 1 hour and 40 minutes on an MK3s.\r\n\r\n=== Together\r\n\r\nGNU GPL for everyone to copy, use, develop and share.
