Retro Water Gun (Fully Functional)

About a year ago I designed a non functional version of this water gun for a friends 300mm scale action figure. Many people asked whether I could print a full scale working replica. Now here we are, a full scale 3D printable replica of the most iconic water gun ever. I modelled this with the intention of making it printable out of PLA, on the most basic of printers with around a 200mm x 200mm print bed. Assembling a functional version will require a lot of extra filing, removing supports, sanding, screwing, glueing and some extra non printed components. I have included the Fusion360 files and a STEP file so it is easy to modify to suit whatever size PVC pipe is available in your region (The STL files will suit a Pipe with an outer diameter of 27mm for the barrell and a pipe with a 14mm diameter for the pump). Other items required for assembly; 1 metre of 4mm vinyl hose (fish tank air hose) 5mm aluminium / stainless / plastic rod for the trigger / valve actuator 6mm x 25mm compr
