This is my take on the Jiangshi AR4 from Destiny. To start off this isn't an easy model, I really struggled to get the long thin parts to stop bending. My advice is don't put the long parts near any heat source until you've glued it all together. Maybe the PLA I used wasn't good enough, I don't know. Also it is very delicate when completed, very spindly and weak, the opposite that a real weapon would need to be to survive combat so I wouldn't use it for cosplay where it will get bashed about a lot. It's a display model really.
Happy to answer any questions and happy printing!

Update 13/8/18 My good model seen in the pictures has warped to hell over time. Don't even attempt to do this in PLA. There will be tears later......
