Summary I asked the kids what they wanted to have me make, and this is the result, a small-ish 60x60x80mm play oven with working door and baking tray. The picture is from a print with my Malyan M150 which developed a partly clogged nozzle during the print making the surface finish not as good as usual, but still works. Just print the parts, and the oven door has 2 little stubs that can be inserted into the fitting holes in the oven. in my case it opens and closes nicely. Print Settings Printer: Malyan M150 Rafts: No Supports: No Resolution: 0.2mm Infill: 20% Notes: I printed with 3 perimeters, first layer height 0.3. Post-Printing Carefully put the door stubs in the provided holes in the oven. How I Designed This This is my first time modeling anything, and first time using FreeCAD. I kept the design simple, and was quite surprised that the door hinges actually work on my first try :)
