Retro Water Gun (Fully Functional)

myminifactory

About a year ago, I designed a non-functional version of this iconic water gun for a friend's 300mm scale action figure. Many people asked if I could print a full-scale working replica. Now we're here - a full-scale 3D printable replica of the most legendary water gun ever. I modeled this with the intention of making it printable out of PLA on basic printers with around a 200mm x 200mm print bed. Assembling a functional version requires a lot of extra filing, removing supports, sanding, screwing, gluing, and some additional non-printed components. I've included Fusion360 files and a STEP file so it's easy to modify to suit whatever size PVC pipe is available in your area (the STL files will fit a pipe with an outer diameter of 27mm for the barrel and a pipe with a 14mm diameter for the pump). Other items needed for assembly: * 1 meter of 4mm vinyl hose (fish tank air hose) * 5mm aluminum / stainless steel / plastic rod for the trigger / valve actuator * 6mm x 25mm compression spring for trigger / valve actuator * Stainless steel pins for trigger and valve actuator (you can use a paper clip in a pinch if needed) * Insertion rubber / rubber mat to make check valves The bottle was designed with a standard soft drink / soda bottle thread, so if you're not prepared to print, join, and seal the bottle, you can always upcycle a 600ml soft drink bottle. While this works, it's still a work in progress, and there are many things that can be improved with the design. As I make improvements, I'll upload them here. Also coming is a test and assembly video.
