Here's the allegations in the Tesla vs. Martin Tripp court case (in Document #1):
Docket for Tesla, Inc. v. Tripp, 3:18-cv-00296-LRH-CBC - CourtListener.com
"Tesla has only begun to understand the full scope of Tripp’s illegal activity,
but he has thus far admitted to writing software that hacked Tesla’s manufacturing operating system (“MOS”) and to transferring several gigabytes of Tesla data to outside entities. This includes dozens of confidential photographs and a video of Tesla’s manufacturing systems. "
"The improper means used by Tripp to acquire and disclose Tesla’s trade secrets include:
a. Breaching specific provisions of the Proprietary Information Agreement;
b.
Writing software to hack Tesla’s MOS;
c. Exfiltrating confidential and proprietary data from Tesla’s MOS for the purpose of sharing the data with persons outside the company;
d. Sending third parties a confidential code or “query”;
e. Taking and sharing with third parties dozens of photographs of Tesla’s manufacturing systems;
f. Taking and sharing with third parties a video of Tesla’s manufacturing systems; and
g. Attempting to conceal electronic evidence of his misappropriation and disclosure of trade secrets."

If those allegations are true (they might not be), the pattern is at minimum industrial espionage, and sabotage for profits isn't an idea far removed, especially considering his TSLAQ affiliations.
I didn't find the paint shop connection though, and since Tripp was employed at GF1, it would be difficult but not impossible to imagine him understanding the paint shop code and procedures to launch successful sabotage. Note that there
was a very interesting increase in paint quality last summer, and paint sabotage would be a particularly nasty variant as it requires a
very expensive recall. So I don't exclude the possibility.
Edit: found the paint shop sabotage allegation, it's in a NYT article quoted by
@EinSV:
TSLA Market Action: 2018 Investor Roundtable
"At 6:30 a.m. on Aug. 18, three robots in the paint shop at the Tesla factory in Fremont, Calif., started malfunctioning. The incident forced a production halt on the Model 3, the key to the company’s future.
Made aware of the stoppage, Mr. Musk went to the factory and worked into the night.
The problem was resolved, but Tesla reached a troubling conclusion: The robots had been infected with malware in an act of industrial sabotage. And though they could not prove it, executives suspected they knew the culprit: a rogue employee, working at the behest of short-sellers."
So I suspect the sabotage (or botched malware attack) did happen, and they suspected Tripp but couldn't link it to him.
Anyway, I think the sabotage angle was, fortunately, just a minor factor - most of the big delays in the Model 3 ramp-up were self-inflicted by Tesla.
