Mixed brake handwheel designs for N-gauge & 2mmFS

N-gauge or 2mmFS. For the spares box: 2 sticks of brake handhweels with 5 curved spokes, and 1 stick each of 4 straight spoked and 6 straight spoked. Other combinations are easily made up, but bear in mind that (currently) the price for four is a minimum for fine detail plastic models, so a set of 3 or less will be no cheaper (let me know if you think this is no longer so). Each stick consists of 16 brake handwheels which can be separated gently with a sharp scalpel, threaded onto the end of a fine wire and held with a tiny drop of glue or sticky paint. There may be a little wax or burr in the central hole, which can be pushed through with the wire after cutting apart, or removed with a fine drill bit in a pin vice.
I have ordered and got some myself in smoothest fine detail plastic, and proved the model is OK. Sometimes Shapeways decline to print models like these because the 'wires' and 'walls' are so fine (I have uploaded several combinations since I first made them) but if that happens when you order them, we may be able to work out a way for me to send you some of my spares.
I use them on models of Warflats, Warwells, Rectanks, Armour Plate Trucks, and Ferryvans, but there are many wagons out there which had manual controls like this. Tell me about any interesting designs or slightly different sizes you want. These are 3mm across, outside diameter, which is a scale 18" (~460mm). Also available/possible in other modelling scales.
