Battery Case for AA and AAA

thingiverse

- Line width: 0.4mm - Wall thickness: 0.8mm - The source file has been uploaded, let's work together to modify it - The "easyPrint" version sets a larger caliber to cope with errors caused by different printers and printing parameters. The consequence is that the battery will be looser when put in. - It was only through this [printed example](https://www.thingiverse.com/make:1036950) that I realized that I made a mistake in the orientation of the letters, sorry. I submitted a corrected version. Different printers or materials and printing settings will bring different printing problems, and the general practice is to enlarge the model to solve the problem. However, enlarging the model may cause other problems, because I design the width of the internal curve to be twice the width of the trace. If possible, modifying the source file is a better way. There are three places to modify: 1. Modify the diameter of the circle to 15.2mm or higher 2. The distance in the pattern feature remains the same as in 1 3. Modify the internal fillet of the four sides to (the value in 1 -0.8mm)/2, and the external fillet value to the internal fillet value + 2.4mm (the width of the outer wall) The software is solidworks (version 2021) 4. I have uploaded the STL version of 18650, but I don't have a physical object in my hand, so I can't verify it. I may need your feedback.
