Both offer much more power than this pump. We offer much improved jet pumps of size 80mm and large 100mm version. If you are interested in finished product you can get it on our official website. Layer hight: 0.2-0.3mm ( on picture is printed with 0.3mm) Any vibration will cause bearings to heat. Shaft- needs to be as straight as possible. 3D printing Aerospace Agriculture Architecture Automotive Aviation Components. Join the GrabCAD Community today to gain access and download Shop.
When the nut is in, just continue printing.īearings and lip seal- just pres them inside (first bearing, then lip seal) The GrabCAD Library offers millions of free CAD designs, CAD files, and 3D models. If its to tight, use soldering iron to heat the nut to press it in easily). In that time you have to insert M8 nut inside (it is tight fit. This is the time you will hit pause button and stop priting complete impeller. Impeller- first calculate time for printing not completed impeller. You can check video of my 30mm bigger jet unit in the added link. 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. Walls are 3mm thick and this makes it very robust design.Įasy to print (hard parts with PLA and gaskets with flexible filament). You can choose between normal difusor or steering difusor. With brass inserts witch are inserted very easily using soldering iron. Great design with big steering angle, low drag for maximum water flow, high angle of attack impeller. My 50mm design water jet thruster for bigger rc boats.
