Lethal Company (or general) Dual SCBA Tanks for Cosplay

INTENDED USE: 
Print Domes, use plastic sheet (24" (circumference) x 14" x 0.020*" for walls. Use Printed Bracket to bolt the two tanks together using the ¼" holes, and ¼" EVA foam for the tank cross straps.

I used a 0.020" sheet of PETG. Need about 24" for the circumference, but the length can be as desired. (24" x 36" sheet will cover 2 tanks and a visor (for the helmet))

ALTERNATE USE (PRINTER ONLY): 
Print Domes, Walls, and Tank straps. Mirrored versions provided for all parts. Tank walls may be scaled vertically as desired for resizing or print volume compliance, and joined using tankjoiner.stl. IMPORTANT: Once the tank is assembled, thin tank walls should be reinforced with filler material (marine foam, casting resin, glue, truck bed liner, etc.). Alternatively, scale and print tankjoiner to fill the internal volume and glue all together. Use a Printed Bracket to bolt the two tanks together using the ¼" holes. Disclaimer: I have not tested this method because I did the above method.
