Water Jet Propulsion Pump Unit Hamilton Water Jet Thruster 50mm

My 50mm design water jet thruster for bigger rc boats. Great design with big steering angle, low drag for maximum water flow, high angle of attack impeller. With brass inserts witch are inserted very easily using soldering iron. You can choose between normal difusor or steering difusor. Walls are 3mm thick and this makes it very robust design.
Easy to print (hard parts with PLA and gaskets with flexible filament). All you need to assemble it is: 2x skateboard bearing (8mm ID, 22mm OD, 7mm thickness), lip seal (same dimension as bearing), 6mm M4 brass thread insert-6x, 7mm M4 brass insert-x3 (for motor mount), 6x M4 bolt, 2x m4 nut, 2x kniping screw, 1x 150mm long shaft 8mm thick with 37mm thread at one end, 1x M8 nut which is inserted in impeller while printing process.
