Battery door for Microsoft Wireless Mouse 3500

thingiverse

I was lucky to have a spare computer mouse with the same model, so I could take precise measurements of the lost battery door. Thankfully, this allowed me to create a new one that fits perfectly. Designing the replacement door proved to be quite challenging due to its complex curved shape. To tackle this issue, I utilized a document scanner to capture an image of another door, which I then imported into SketchUp and carefully traced over the lines. When recreating the original design, I had to enlarge several tiny details so they could be printed using a 0.4mm nozzle; if I had access to a smaller nozzle, I would have definitely used it. Although my replacement door doesn't fit perfectly, it only requires a minimal amount of sanding and cleaning to function properly. To print the new door, I chose to use 100% infill with no support material in ABS plastic, as the tiny flexible areas may break if printed in PLA. The design was created in SketchUp, refined with Microsoft 3D Builder, sliced using Cura, and finally printed on my Robo 3D R1+ 3D printer.
