Aerospike rocket engine

Hello Makerworld community !For my first design and contest on this platform I make a rocket thruster inspired from the work of Leap71 company. This firm is a pioneer in Computational Engineering which can generate parts, structures or entire machine with an open-source software which translate human engineering knowledge into algorithms. For more information on this company : https://leap71.com/ I redesign one of their AI generated rocket engines. I simplified and sized it to print it on a Bambulab 256x256x256mm bedding. All input/output ports communicate with real ducts and tubes (without the 120° cut). Here is the parts of the model :Printing Material:I printed the model using PLA- PLA Silk Copper- PLA Matte Ash Grey- PLA Basic black Bill of MaterialsI am currently using it as a fixing- 4x Screws M8*1.25- 2x Nuts M8*1.25 Next features :Add lock pins instead of M8 boldsDevelop an educational model with different colour parts to understand which input-output communicate with
