Note: I wasn't able to upload profile due to “Slicing timeout” in Maker World. But I provided 3mf file with all the settings for you, you can download it from RAW Model Files section. Please download it and open in it Bambu studio.

Space helmet for kids with lifting visor.

• Inside diameter is 220 mm and bottom hole in bayonet is about 192 mm in diameter.
• You can print it from colored filament, but I recommend to print it, sand it and the spray it with color. Shape is smooth and easy to sand.
• Parts are meant to be glued together, see images for reference. Superglue works great.
• For earpads, cut piece of foam and clamp it toghether between 3D printed parts using 2pcs M3x10 screws.

Transparent visor

• For visor, use 0.5 mm transparent sheet and hot moulding (heat it up in the oven and stretch it over the mould. You can later apply smoke transparent color paint.

Other notes

• Corrugated hose is not 3D printed. It's just some part I found somewhere.
• Helmet, visor and bayonet are also split into several parts so they can be 3D printed on smaller printers (220 x 220) too. In such case, print provided pins - these will help you alignt parts together. Bambu can print them in one pieces.
