Cables

Try to get the lengths right. Slack can be annoying.

For each tibia, one CAN and one power cable. Length: 290mm.
For each femur, one CAN and one power cable. Length: 340mm.
Power dist board -> left qdd: one power cable. Length: TODO.
Power dist board -> right qdd: one power cable. Length: TODO.
pi3hat -> left qdd: one CAN cable. Length: TODO.
pi3hat -> right qdd: one CAN cable. Length: TODO.
power dist board -> pi3hat: one power cable and one (optional) CAN cable. Length: TODO.
Solder a xt30 connector to the fan to connect to the power dist board.

Print all the .stl files. Some files have (or will have) a .3mf version if the print is difficult. Notes:

The femurs and tibia print vertically. Adding a brim is recommended.
Print the files with names starting with FLEX in flex filament.
The tyres need to be softer than what you would get with the regular slicer settings. See the .3mf file, or experiment with slicer settings.
The parts are designed to be printed with a maximum overhang threshold of 60 degrees. Anything lower may result in unwanted support (may be hard to remove).
Files with x2 in the name need to be printed twice.
There are several versions of the battery holder depending on the battery dimension.
