SU HS2 Carburetor Velocity Stack

I created this velocity stack based on pictures I found online. It mates with a K&N air filter (model RU-4410 or RU-2990) There are left and right variations of the velocity stacks. I also added a flange at the end of the stack to the neck of the filter sit perfectly. Back of the stacks are hollowed to save filament material I printed mine in Polycarbonate (PC) which should withstand the gasoline and engine temperatures. Bolts are based on the stock air filter bolts. Printed at: 0.20mm with supports for the stacks 0.16mm without supports (with brim) for the bolts Hope this helps someone!
