Kino Wheels Housing.

thingiverse

A housing I designed specifically for the Kino Wheels open-source project can be found at kinowheels.com, facebook.com/kinowheels, and facebook.com/groups/kinowheels. When printing this housing, common sense dictates that it needs support. Printing it like a bowl is one effective way to do so, especially when handles need support in the middle but not for all small holes. The shafts I've made are out of aluminum, but printing should be sufficient for home use. All the holes in the back of the wheels are designed for threaded steel inserts that are 18mm long. Unfortunately, they didn't work as well as I had hoped. M5x20mm hardware is used around the case and M5 countersinks are used for the wheel lock-off. I think M5 x 35mm hardware should be used for the wheel knob. There's a bit of an issue below the encoder saddle, but my Fusion skills aren't quite at Tony Stark level yet. The bearings used in this housing are 30x32x7mm and need to be convinced by hand to fit properly. The wheel knob bearings, on the other hand, are 5x10x4mm and were purchased from an RC car shop. Square holes have been added to accommodate aluminum plates for making mounting holes. I believe these plates are 12mm thick and approximately 60x60 in size; please measure carefully. The bottom of the housing was printed at .35mm thickness, while the top was printed at .2mm thickness. The finer print resolution looks better but takes significantly longer to complete.
