A customizable filiment odometer. Choose the number of digits you would like displayed and the units (cm and inches). Also because I'm a nerd feel free to express your values in either Decimal, Oct, or Hex (no binary at this point but if there is desire for it let me know and I'll design custom gears to replace the Decimal option)
I do not have a functioning printer so this is very much a work in progress, let me know if there are any problems with printing or the mechanism and I will do my best to resolve them.
Design inspired by ErikJDurwoodII but this is very much a seperate project to his work

Number gears are comprised of 3 pieces (for easier printing). Asembled them with a full nub on the right (if looking at the numbers right way up) and the single nub of the far side (see below) Single nub location: Decimal (pointing between 5 & 6), Oct (pointing between 4 & 5), Hex (Pointing between 9 & A)
There is an option for a printed shaft, I have a feeling that plastic on plastic will bind a lot, I recommend using a small piece of steel rod the SCAD is configured to use a 2mm rod by default
The top cap portion is intended to be printed in 2 halves (this is for printability), if there is desire for a single piece option (you will need to print supports) I will include it.
Finally based on the resolution of your printer I don't recommend printing the numbers on the wheels, instead use a sharpe and write them on after (but there is an option to include them)
