Water wheel (d = 400mm, no screw / no glue kit)

thingiverse

I'm designing a water wheel for one of my projects, with a diameter of 400 mm. The design is a "no screw" and "no glue" kit solution, where printed parts fit together firmly and some are secured in place using black nylon wire strips that are 4mm wide. The parts were printed using ABS (110°C for the first five layers, 100°C afterwards, with a honeycomb infill of 20%). I used an Original Prusa i3 MKII printer without any issues, even though it was printing in a room with a temperature of around 26°C. It's possible to avoid printing the largest part (side_plus_paddles.stl) by replacing it with a simpler part (side.stl) and then designing the paddles separately. However, this would require using glue or acetone to bond the parts together. I'm confident that the design can be scaled up or down slightly, and I recommend printing a smaller number of parts at first to ensure they fit together properly, especially if you're using PLA or PETG. It's also a good idea to use brims with a minimum thickness of 2mm. I used 3mm brims on my print and it turned out well. You can design your own center for the water wheel using a ball bearing of your choice. I'll be posting my design soon. One final note: the water wheel looks great in brown color, but keep in mind that there's an older version of the design (with holes for pegs) and some parts haven't been fully cleaned of brims yet. I'll post better photos once I've taken new ones. Print Settings: * Printer: Original Prusa i3 MKII * Supports: No * Resolution: 0.2 * Infill: 20%
