I reconstructed this generator from the warhammer game "dawn of war".

If you want to change something, I also uploaded the Autodesk Fusion 360 file and the .step file of the whole project.

!!! Pls. note, that you have to upscale the model/the pieces by a factor of 1.5 so that you can use it for the normal tabletop!!! (I made the model to tiny, but I don´t wanted to rework everything (because I´m lazy))

Please note that for some 3d-printers some of the parts have to be turned to ensure an optimal round shape (e.g. for the tubes):

Part_A_connector: vertical Part_B_cover: horizontal Part_C_main_casing: horizontal Part_D_main_body: horizontal Part_E_pipe_1: vertical Part_F_additional_part_1: horizontal Part_G_additional_part_2: vertical Part_H_additional_part_3: vertical Part_I_additional_part_4: vertical Part_J_pipe_2: vertical
