My Father's Work - Knowledge tracker fix

The wooden tracker pieces that the game provides to track recorded knowledge are gorgeous but a little top-heavy, and they regularly tip over on me. This is a super-quick fix which broadens the base a little bit.

I recommend printing these upside down and with a manual 5mm support added to the hole. I've added the OpenSCAD file to allow you to change the size of the hole from the 8mm default (use the "cutout" parameter for this); 8mm works perfectly for me as a friction-fit, but you may need to increase/decrease that a bit based on your slicer, printer, and meeple variations.
