If woodchucker is referring to me, here it is:
Here's a picture of the crossfeed dial printed out in PETG. The dial was printed with the side where my index finger is facing down on on the build plate. Used Prusa Slicer at .2 layers with a .4 nozzle.
I just need to make a sleeve with an index line and lock screw to slide over the crossfeed screw base which I haven't gotten around to it yet and install he new dial and base on the lathe. I think, for me, the hard part is over on this part which is designing the dial in Fusion 360.
Addressing parametrics, Fusion 360 incorparates a table of change values where you name the variable and put in a number , like a spreadsheet, and the value can be input direct or calculated from other input numbers or named variables. You can get as basic or as complicated as you want. I included a picture of the values that I used to make the hash mark lengths on the dial. The numbers were put into the 3D model manually so I could play with the lengths by plugging different values in to change the model until it looked right. The 1, 5, and 10 thousandth hashes are different lengths as you can see in the picture. Parametrics could have been used to dimension the dial size and thickness as well but for some reason I just put those dimensions directly into the drawing.
Was happy when the 3D model and 3D print was done because it gave me a headache.
Hope this helps.
Best regards.
