Does this part insulate the heat on the motor well? I have the stock aluminum assembly on my CR10-S5, and it absorbs too much heat that PLA can't be printed well.

I'm guessing this part in PETG would be the best insulator, right?

I have an ABS one. No such problems.

Has anyone made this yet out of PLA? And if so has anyone had a heat problem? im makeing this out of PLA with a 50% infill for strenght was wondering would it handle the heat?

did this ever work with pla?

I strongly advise everyone not to use PLA here. It will soften and brake very quick from motor heat.

also is there a wire on the mainboard for the sensor? and what about the software will it need to be changed?

TH3D.com makes an EZ-Out which will do filament out sensing on CR10 (I have it) with their firmware. This requires some tech stuff by you. I am very happy with their firmware and products (just a customer).

On CR10S sensor and the wire is the stock components. There is no such on basic CR10, but it might be some way to implement the sensor. Moreover, CR10 has got a half less onboard memory, so that can be the problem, because my custom marlin eats about 70% of EEPROM of CR10S with bed leveling.

print in petg not abs

petg holds up to approx. 80 deg, so in some marginal cases especially if u use enclosure it can be damaged by heat from motor, which can safely operate up to ~85 deg and even higher.
[just an opinion]

It's not touching the lead screw?

Sure not. There is an overkill clearance in-between and fillament path is also strait to avoid any additional friction.
