OO/HO Gauge Wheels

FDM printable OO/HO Gauge wheels, compatible with commercial wheelsets with axles 25.65mm long, ending in points. In general, I think you're better off buying cheap plastic HO wheels from china, but it was a fun experiment and it provides future options for non-standard styles and sizes of wheel. I tested them on my garden OO gauge railway (PECO track and pointwork, generally imperfectly laid and a bit wonky) and they are reliable! When slicing, make sure to use the minimum layer height possible for the flange. Prusaslicer's variable layer height is useful for this. There are two types of these wheels: - "Flat": intended to slot onto a 2mm diameter, 25.65mm long pointed axle (the wheels are flat). - "Pointed": intended to slot onto a 2mm diameter, 18.5mm long flat-ended axle (the wheels have a pointed cone). Both types are used the same way - two spacers are slotted onto the centre of the axle first, and then the wheels should fit onto the ends of the axle, with the spac
