Brio steam locomotive replacement front/battery hatch

To complete it, you'll need a bit of aluminum foil to connect the battery to the pad and a screw of the right size. I've uploaded the OpenSCAD file so you can modify the design if you want to use a screw with different dimensions than the one I used. I printed using ABS plastic with a 0.4mm nozzle. The design comes with built-in supports that need to be cut away during post-processing - no additional supports are necessary.
