The first time I ran my harness with the standard design, three things happened.
The motors got *really* hot, way above their spec
this softened the 3D printed stuff, especially the sensor plate
because the sensor plate is like a washer for the main mounting bolts, when it softened the motor twisted in the mount
These mods fixed these issues and some others.
There are shims so it fits my rigs 4080 profile, you will not need them if the original design fits your profile
An aux mount that holds the motor-end square so it doesn't twist or sag, relieving some pressure on the main motor mounted bolts and associated printed parts
includes a fan mount for 4020 fan, which can be sliced off if you don't want it
my heatsinks are held on with heat conductive tape
the fans make a huge difference to temperature
The sensor plate is simplified, it's a single thickness so it's easier to print and stronger than the original. Print it solid (100% infill or max out top/bottom layers)
A fan cowl just for fun
A motor housing to make it look tidy, it clips on
The lever is modified to take a piece of steel plate with M4 taps. This works really well but probably not much use for anyone. I have a better idea for this for future, but the darwinnite lever in the simhub discord seems like a fine alternative to the original. I never used the flanges in the original design, they were terrible quality.
Main motor mount is not modified, use the original
The fans are 12v https://www.amazon.com/gp/product/B072JK9GX6/ and run off the main PSU using https://www.amazon.com/gp/product/B00CGURKUA/
They are attached using standard fan screws
The optional fan cowls are attached to the fan frame using standard fans screws
Heatsinks

Note: the ends of my motors were slightly concave, so I only put tape around the edges; otherwise it did not adhere very well.
Amps. I run my motors at 3.8 amps and get zero slipping, even though I have the harness pulling really hard. However, run your motors at the lowest value that works for you; the build instructions say max. 3.2 amps. Go above that at your own risk and monitor temps. If the motors are not cool, dial it back.
