This is a mini recreation of the Sapphire nitro+ rx570/580/590, will be compatible with other mini pc parts I'll make in the future. If u want to 3d print it I recomend you to do it by pieces (uploaded already) with the important details looking up. If u want to paint it (which I recomend) paint before putting it together, it'll be easier, trust me.
Push Plastic PLA
Everything that needs support are the heat pipes and the pcie slot/lane. No ironing.
For assembly: First glue together the 2 central pieces (the ones with the heat pipes), place the backplate perfectly aligned with the central pieces on top (above the sapphire logo), then the fan frame on the other side. Place the pcie slot 7mm away from the sapphire logo, and lastly the fans... pretty obvious.
