1:2 scale Samus' Armcannon (Metroid Prime)

thingiverse

This is approximately a 1:2 scale replica of Samus' Arm cannon from the Metroid Prime games. The cannon is made up of several parts to emulate the way it morphs and shifts when selecting different beams. The light is an RGB LED lamp I gutted and disassembled, the model I bought needed an extra 5 pin cable (used for led strips) to connect the LEDs to the transformer, I have included the housing I used to hold it in place but YMMV depending what electronics you can procure or build yourself. The transformer will be hidden inside her arm, but that piece is yet to be made. The halves are held together with two M6 x 60mm (or 2 1/2") screws and self locking nuts, a similar screw but 50mm long (2") is used for the elbow. The parts shift using simple wedges pushing and sliding onto other wedges, this system is admittedly far from perfect, and I intent to iterate on it, and perhaps try a new design in the future. The nozzle can be opened up either with by twisting the center splitter or with the individual hinges of each quarter. I used silicon grease to lube every moving part. This cannon will be part of a larger print, which is the remainder of Samus herself (standing 1m tall), those files will be on a different page and linked here when its done. "Clear" or "Transparency" pieces should be printed with colorless filament, with few perimeters and little infill for better illumination, if you have dual extrussion you may be able to print the ice and wave transparencies with their green shells on top, but I choose to glue them with liquid silicone. The "glow" pieces should be made with green or yellow "glow in the dark" filament. Everything else can be made in green (silver is also a good alternative), with optional colors for the beam buttons. The elbow_cover should be made with gold colored filament, silk PLA would be great but remeber this figure is gonna be quite large, may want to go with something cheaper or just paint it. These parts must be duplicated and mirrored in the slicer: main_side plasma_transparency screw_lid ext_dome_1 ext_dome_2 wave_transparency_1 wave_transparency_2 side_slide glow_short glow_long LED_lampPCB_holder (mirroring not necessary) These parts must be printed 4 times: nozzle_slide nozzle_quarter Both peg types should be duplicated at least once each. Everything else is printed once. Model was extracted from Metroid Prime 3 using Metaforce.
