ACR/ Masada Airsoft Stock Hinge

thingiverse

UPDATE 3/4/19: First prototypes printed, hinge very close to exact fit but needs some work. Holes too tight of clearance to fit hinge pin, needs greater clearance with gun. Everything slides as expected, update files soon. UPDATE 3/15/19: This design more problematic than thought. Hinge takes couple iterations, still need to work out clearance issue on button. Design getting closer however, may have update in few weeks. After purchasing secondhand Masada airsoft gun, discovered stock hinge broken after receiving gun. Rather than buying another stock for $35 or more, decided to print own as only one piece is broken. Design isn't quite final but will be printing test parts soon and finalizing this in near future. This designed to fit with what assume are stock A&K Masada airsoft parts. My gun has no branding but from research done am pretty confident it's an A&K. At very least, the parts at least look same. No additional hardware needed if you have original nuts and bolts. Print with butt side on buildplate, one with semi circle cutout. Supports recommended. Would recommend at least 4 shells and 15% infill if intend this to last. Stock will be snug but should slide in and lock well with tabs. Prototypes had sturdier feel than original parts. Will upload more pictures and source files when design is complete.
