Waterwheel

thingiverse

This is my design of a waterwheel which i am going to attach to water wheel house feature. I will post the rest of the design for that once they are complete. The wheel is design to work with two bearings and an m4 bolt with two nuts. Size: Diameter: 100mm, thickness: 30mm Instructions Extra materials you need, all found on ebay: 2 x BEARING TYPE: 684 4x9x4mm 1 x M4 Bolt (min 35mm in length) 2 x M4 nuts I printed this with abs in two parts hence why i have put both the full and the divided files. I then glued them together with acetone. It actually printed very well and only had 2 small separations on two different paddles but they where quick to fix with acetone. I recommend that you print this with a brim of around 10 mm so you don't get any lift. The over all assembly is quite easy with one nut going into the closed off part and then a bearing over it, then just put the other bearing in the open part and run a m4 bolt thru them. The idea here is that the m4 bolt screws into the nut and then as the wheel turns the nut has no where to catch so it doesn't come undone. So to lock it in i recommend putting slight pressure on the m4 bolt to screw it in. To unscrew it pull the m4 while unscrewing. Both tasks take about 15 seconds, in the end you still may feel it's lose but give it a try. The wheel has been spinning for 14 days non stop and so far it hasn't come off. If you turn the wheel upside down and spin it, eventually it comes off but it was designed to turn at 90 degrees. If you feel that it may come off you could possibly glue the nut to the m4 bolt just make sure you do it with both bearing in the m4, then you just need to push it into place.
