Side Hustles for Mech Engineers

I love my day job as an engineer designing conveyors. However, I would like to use my experience and degree to make a bit more cash outside of work hrs.

I know this is difficult, depending on the venture. Legal issues, insurance (if designing) and software costs. Can’t utilise work resources (such as software) as they would then own the I.P.

Just feel like I could be doing more, curious to see if anyone else is in the same boat and if anyone else is currently doing this.

Cheers!
