About this 3D model

Ana's rifle from Overwatch. I've tried to keep supports to a minimum while also getting as much details as I can on each part. There are slots for 6x3mm magnets on the handle and barrel to make it easier to travel with. There's space in there for 2 stacked ontop of eachother. I printed the parts at 0.15-0.2mm layer height, 2 perimeters at 8% infill in ABS and acetone-welded the flat surfaces together.In hindsight, adding some pegs to align them better would have been better. So I'm trying that out on my next print. I went through about 2/3rds of a spool printing this, so with supports I think it was around 600-700g total. (possibly less since I had to redesign and reprint some fragile parts).
